Hi I have made use of a python library to collect the data of a topic. For example I chose the topic of New york and I have retreived the content with the following code:
import wikipedia
f2 = open('newyork', 'w')
ny = wikipedia.page("New York")
f2.write(ny.content.encode('utf8')+"\n")
I am able to extract the information in the format below:
New York is a state in the Northeastern United States and is the 27th-most extensive, fourth-most populous, and seventh-most densely populated U.S. state. New York is bordered by New Jersey and Pennsylvania to the south and Connecticut, Massachusetts, and Vermont to the east. The state has a maritime border in the Atlantic Ocean with Rhode Island, east of Long Island, as well as an international border with the Canadian provinces of Quebec to the north and Ontario to the west and north. The state of New York, with an estimated 19.8 million residents in 2015, is often referred to as New York State to distinguish it from New York City, the state's most populous city and its economic hub.
With an estimated population of 8.55 million in 2015, New York City is the most populous city in the United States and the premier gateway for legal immigration to the United States. The New York City Metropolitan Area is one of the most populous urban agglomerations in the world. New York City is a global city, exerting a significant impact upon commerce, finance, media, art, fashion, research, technology, education, and entertainment, its fast pace defining the term New York minute. The home of the United Nations Headquarters, New York City is an important center for international diplomacy and has been described as the cultural and financial capital of the world, as well as the world's most economically powerful city. New York City makes up over 40% of the population of New York State. Two-thirds of the state's population lives in the New York City Metropolitan Area, and nearly 40% live on Long Island. Both the state and New York City were named for the 17th century Duke of York, future King James II of England. The next four most populous cities in the state are Buffalo, Rochester, Yonkers, and Syracuse, while the state capital is Albany.
The earliest Europeans in New York were French colonists and Jesuit missionaries who arrived southward from settlements at Montreal for trade and proselytizing. New York had been inhabited by tribes of Algonquian and Iroquoian-speaking Native Americans for several hundred years by the time Dutch settlers moved into the region in the early 17th century. In 1609, the region was first claimed by Henry Hudson for the Dutch, who built Fort Nassau in 1614 at the confluence of the Hudson and Mohawk rivers, where the present-day capital of Albany later developed. The Dutch soon also settled New Amsterdam and parts of the Hudson Valley, establishing the colony of New Netherland, a multicultural community from its earliest days and a center of trade and immigration. The British annexed the colony from the Dutch in 1664. The borders of the British colony, the Province of New York, were similar to those of the present-day state.
Many landmarks in New York are well known to both international and domestic visitors, with New York State hosting four of the world's ten most-visited tourist attractions in 2013: Times Square, Central Park, Niagara Falls (shared with Ontario), and Grand Central Terminal. New York is home to the Statue of Liberty, a symbol of the United States and its ideals of freedom, democracy, and opportunity. In the 21st century, New York has emerged as a global node of creativity and entrepreneurship, social tolerance, and environmental sustainability. New York's higher education network comprises approximately 200 colleges and universities, including Columbia University, Cornell University, New York University, and Rockefeller University, which have been ranked among the top 35 in the world.
== History ==
=== 16th century ===
In 1524, Giovanni da Verrazzano, an Italian explorer in the service of the French crown, explored the Atlantic coast of North America between the Carolinas and Newfoundland, including New York Harbor and Narragansett Bay. On April 17, 1524 Verrazanno entered New York Bay, by way of the Strait now called the Narrows into the northern bay which he named Santa Margherita, in honour of the King of France's sister. Verrazzano described it as "a vast coastline with a deep delta in which every kind of ship could pass" and he adds: "that it extends inland for a league and opens up to form a beautiful lake. This vast sheet of water swarmed with native boats". He landed on the tip of Manhattan and perhaps on the furthest point of Long Island. Verrazanno's stay in this place was interrupted by a storm which pushed him north towards Martha's Vineyard.
In 1540 French traders from New France built a chateau on Castle Island, within present-day Albany; due to flooding, it was abandoned the next year. In 1614, the Dutch under the command of Hendrick Corstiaensen, rebuilt the French chateau, which they called Fort Nassau. Fort Nassau was the first Dutch settlement in North America, and was located along the Hudson River, also within present-day Albany. The small fort served as a trading post and warehouse. Located on the Hudson River flood plain, the rudimentary "fort" was washed away by flooding in 1617, and abandoned for good after Fort Orange (New Netherland) was built nearby in 1623.
=== 17th century ===
Henry Hudson's 1609 voyage marked the beginning of European involvement with the area. Sailing for the Dutch East India Company and looking for a passage to Asia, he entered the Upper New York Bay on September 11 of that year. Word of his findings encouraged Dutch merchants to explore the coast in search for profitable fur trading with local Native American tribes.
During the 17th century, Dutch trading posts established for the trade of pelts from the Lenape, Iroquois, and other tribes were founded in the colony of New Netherland. The first of these trading posts were Fort Nassau (1614, near present-day Albany); Fort Orange (1624, on the Hudson River just south of the current city of Albany and created to replace Fort Nassau), developing into settlement Beverwijck (1647), and into what became Albany; Fort Amsterdam (1625, to develop into the town New Amsterdam which is present-day New York City); and Esopus, (1653, now Kingston). The success of the patroonship of Rensselaerswyck (1630), which surrounded Albany and lasted until the mid-19th century, was also a key factor in the early success of the colony. The English captured the colony during the Second Anglo-Dutch War and governed it as the Province of New York. The city of New York was recaptured by the Dutch in 1673 during the Third Anglo-Dutch War (1672–1674) and renamed New Orange. It was returned to the English under the terms of the Treaty of Westminster a year later.

Sorry for the long post and please forgive me as I have very little knowledge of python.
All advice and help is greatly appreciated.
Thank you.

Current Problem
Hi osantana,
I have tried the code that you have provided as shown below:
import wikipedia
import re
f2 = open('osantana', 'w')
ny = wikipedia.page("New York")
section_title_re = re.compile("^=+\s+.*\s+=+$")
raw_content = ny.content
content = []
skip = False
for l in raw_content.splitlines():
line = l.strip()
if "== References ==" in line.lower():
skip = True # replace with break if this is the last section
continue
if "== Further reading ==" in line.lower():
skip = True # replace with break if this is the last section
continue
if "== External links ==" in line.lower():
skip = True # replace with break if this is the last section
continue
if section_title_re.match(line):
skip = False
continue
if skip:
continue
content.append(line)
content = '\n'.join(content) + '\n'
f2.write(content.encode('utf8')+"\n")
It works fine for all except this 3 part:
Original File:
== References ==
Index of New York-related articles
Outline of New York – organized list of topics about New York
== Further reading ==

Result of the code:

The headings were removed but the content is still intact.
I'll assume that Reference/Further Reading are not the last sections in all pages. If those topics are the last sections replace the highlighted code below with a break command.
import re
def parse(raw_content):
section_title_re = re.compile("^=+\s+.*\s+=+$")
content = []
skip = False
for l in raw_content.splitlines():
line = l.strip()
if "= references =" in line.lower():
skip = True # replace with break if this is the last section
continue
if "= further reading =" in line.lower():
skip = True # replace with break if this is the last section
continue
if section_title_re.match(line):
skip = False
continue
if skip:
continue
content.append(line)
return '\n'.join(content) + '\n'
print(parse(ny.content))
For problem 2 you could do something like this
contents = re.sub('=+\s*.+\s*=+', '', contents)
Just remember to import re, the regular expressions module.
The method being used is re.sub(pattern, repl, string). pattern is a regular expression pattern* (the re documentation provides an overview on it).
repl is what you want to replace all occurrences of the pattern with. In this case you want to remove the pattern, so just use an empty string as the replacement.
string is of course the string you're performing the substitution on. This method returns the final result, so if you want to overwrite the original string, just assign the returned value back to the input string.
Here's the pattern I used explained just in case. '=+\s*.+\s*=+' means any part of the string where there is one or more equal sign (=+), followed by zero or more spaces (\s*), followed by one or more of any character (.+), followed again by zero or more spaces (\s*), finally ending with one or more equal signs (=+).
For problem 1 I'd say you could probably accomplish what you want to using regular expressions as well, and the re module makes it pretty easy. The link I gave above should help.

My goal is to make this a dictionary where the keys are the years and the values are the events on the timeline. However, I'm having a little trouble.
I want to first split the timeline into a list like so: {key, value, key, value} and then turn it into a dict. I want to split the string 5 or 6 characters before " - " in order to accomplish this, but I have no idea how to do that. Can anyone help me?
EDIT:
Came up with this possible solution -
timeline = timeline.replace("\n","")
timeline = timeline.replace("\\","")
timeline = timeline.replace("19","zz19")
timeline = timeline.replace("20","zz20")
timeline = timeline.split(" - ")
So basically I end up with this:
['zz1961', 'Second child, John, is born. zz1963', 'Is ordained as a Presbyterian minister. Makes his on-camera debut as host of a series of 15-minute episodes for children produced in Toronto. The program is titled "Mister Rogers." zz1964', 'Returns to Pittsburgh and turns his 15-minute show into the half-hour "Mister Rogers\' Neighborhood." zz1968', '"Mister Rogers\' Neighborhood" debuts on PBS and wins the first of its several Emmy Awards. Rogers is appointed chairman of the Forum on Mass Media and Child Development of the White House Conference on Youth. zz1969', "Wins the first of his two George Foster Peabody Awards for television excellence. Fred Rogers readies the opening pitch to start the Pirates' season in zz1988. (Post-Gazette archives) zz1971", 'Forms his production company, Family Communications Inc. zz1975', 'Ceases production on "Mister Rogers\' Neighborhood," which continues to air on PBS in reruns. zz1978', 'Creates the PBS series "Old Friends, New Friends," focusing on older people. zz1979', 'Production resumes on "Mister Rogers\' Neighborhood." zz1981', 'Eddie Murphy plays an inner-city children\'s show host in his "Mister Robinson\'s Neighborhood" sketch on "Saturday Night Live," which is probably the most famous of the many "Mister Rogers" spoofs. zz1984', "The Smithsonian Institution in Washington makes Fred Rogers' trademark sweater part of its permanent collection. Rogers forces the fast-food chain Burger King to remove ads featuring a Mister Rogers lookalike. zz1987", "Appears on a children's TV show in the Soviet Union and reciprocates by having a Soviet host appear on his show later in the year. zz1989", '"Mister Rogers\' Neighborhood of Make Believe" opens as an attraction at Idlewild Park. zz1990', "Sues the Ku Klux Klan and forces the organization to stop playing racist telephone recordings featuring imitations of Fred Rogers' voice, speech patterns and theme song. zz1991", 'Tapes spots for PBS on the eve of the Gulf War to reassure children that they will be all right if hostilities occur. zz1996', 'TV Guide names Fred Rogers one of the 50 greatest TV stars of all time. Rogers makes his only appearance as someone other than himself when he takes a cameo role as a preacher on the drama series "Dr. Quinn, Medicine Woman," which he says is one of his favorite shows. zz1997', 'Is honored for lifetime achievement by the National Academy of Television Arts and Sciences (who hand out the Emmy Awards) and by the Television Critics Association. Named Pittsburgher of the Year by Pittsburgh magazine. zz1998', "Gets a star on the Hollywood Walk of Fame. The Pittsburgh Children's Museum opens a Mister Rogers exhibit. zz1999", 'Is inducted into the Television Hall of Fame. zz2000', 'Unveils a planetarium show featuring "Neighborhood" characters at the Carnegie Science Center; ceases production on "Mister Rogers\' Neighborhood." zz2001', 'Last original episodes of "Mister Rogers\' Neighborhood" airs on PBS. zz2002', 'In July, is presented the Presidential Medal of Freedom, the nation\'s highest civilian honor.

The theme: "Children\'s Wishes, Dreams and Imagination." zz2003', 'Dies of stomach cancer at age 74.']
So I would want to split this string by "zz", the only problem is I can't split it twice because it's already a list. Obviously I could concatenate the list, but then I would just run into the same problem as now.
Tried doing this:
for i in timeline:
i = i.split("zz")
But it doesn't work :(
You could make the dictionary like this:
parts = timeline.replace('\n','').split(" - ")
d = dict()
for x in range(len(parts) - 1):
d[parts[x][-4:]] = parts[x + 1][:len(parts[x+1]) - 4]
Since your delimiter is clearly " - " and by doing so you would have set of items like:
'1961'
'blablablablabla. 1963'
'blablablablabla. 1968'
'blablablablabla. 1969'
'blablablablabla'
Then you only need to pair your last 4 characters in the text with the next text except the last four characters. Thus, simple split and slice will work for you.
Using this to show the result:
for a in d:
print(a + " " + d[a])
This is what I got:
1975 Ceases production on "Mister Rogers' Neighborhood," which continues to air on PBS in reruns.
1968 "Mister Rogers' Neighborhood" debuts on PBS and wins the first of its several Emmy Awards. Rogers is appointed chairman of the Forum on Mass Media and Child Development of the White House Conference on Youth.

2003 Dies of stomach cancer at age
1998 Gets a star on the Hollywood Walk of Fame. The Pittsburgh Children's Museum opens a Mister Rogers exhibit.
1979 Production resumes on "Mister Rogers' Neighborhood."
Note that dictionary is unordered. Use OrderedDict if you need it to be ordered.
The ordered dictionary is as easily done as dictionary like this:
import collections
parts = timeline.replace('\n','').split(" - ")
od = collections.OrderedDict()
for x in range(len(parts) - 1):
od[parts[x][-4:]] = parts[x + 1][:len(parts[x+1]) - 4]
And using this:
for a in od:
print(a + " " + od[a])
The result will be ordered:

Let's split using regex!
import re
stripped_string = timeline.replace('\n', '').strip() # whitespaces go away
splitted = re.split('(\d{4}) - ', stripped_string) # split to ['', year1, event1, year2, event2, ...]
lst = splitted[1:] # first empty split goes away
keys = lst[0::2] # get years
values = lst[1::2] # get events
dic = dict(zip(keys, values))
You could make it more specific further. For example, if you know that years are 19xx or 20xx, then:
splitted = re.split('((?:19|20)\d\d) - ', stripped_string)
will do as well.
Also, since you have keys and values explicitly, you could do several things easily, like stripping whitespaces of each element in values. For example:
values = [event.strip() for event in lst[1::2]]
Here's the result:
>>> print("\n".join("{}: {}".format(k, v) for k, v in dic.items()))

I have an unstructured text which I want to convert into 1 line and remove all the punctuation marks.
For the punctuation marks i used the following solution Best way to strip punctuation from a string in Python
How can i reformat the unstructured text into 1 line by using python?
Example 1:
The Bourne Identity is a 2002 spy film loosely based on Robert
Ludlum's novel of the same name. It stars Matt Damon as Jason Bourne,
an amnesiac attempting to discover his true identity amidst a
clandestine conspiracy within the Central Intelligence Agency (CIA) to
track him down and arrest or kill him for inexplicably failing to
carry out an officially unsanctioned assassination and then failing to
report back in afterwards. Along the way he teams up with Marie,
played by Franka Potente, who assists him on the initial part of his
journey to learn about his past and regain his memories. The film also
stars Chris Cooper as Alexander Conklin, Clive Owen as The Professor,
Brian Cox as Ward Abbott, and Julia Stiles as Nicky Parsons.
The film was directed by Doug Liman and adapted for the screen by Tony
Gilroy and William Blake Herron from the novel of the same name
written by Robert Ludlum, who also produced the film alongside Frank
Marshall. Universal Studios released the film to theaters in the
United States on June 14, 2002 and it received a positive critical and
public reaction. The film was followed by a 2004 sequel, The Bourne
Supremacy, and a third part released in 2007 entitled The Bourne
Ultimatum.

Government
The township is governed by a three-member board of trustees, who are elected in
November of odd-numbered years to a four-year term beginning on the following
January 1. Two are elected in the year after the presidential election and one
is elected in the year before it. There is also an elected township clerk, who
serves a four-year term beginning on April 1 of the year after the election,
which is held in November of the year before the presidential election.
Vacancies in the clerkship or on the board of trustees are filled by the
remaining trustees.
As you can see in the previous examples. The text have different formats. How can I turn every single text into 1 line?
This is pretty straight forward - basically, other than the punctuation, you are now also looking to eliminate the line endings.
So, you can simply do:
import string
exclude = set(string.punctuation + "\n\t\r")
print ''.join(ch for ch in input_string if ch not in exclude)
input_string = """The Bourne Identity is a 2002 spy film loosely based on Robert Ludlum's novel of the same name.

I have a feature class which contains 40,000 mailing addresses. Each address contains the street address, city, state and zipcode separated by spaces.
Example 1: 123 Northwest Johnson St Cleveland Ohio 12345
Example 2: PO Box 3 Pine Springs Ohio 12345
I want to pull out just the street addresses. How do I say: trim off the string starting at the 3rd or 4th to last space?
Thanks. Any help would be appreciated. I'm trying combinations of split, trim, etc. but can't get it right.
This is how you can do it in pure Python, I am not sure about differences when using ArcGIS:
ad1 = "123 Northwest Johnson St Cleveland Ohio 12345"
ad2 = "PO Box 3 Pine Springs Ohio 12345"
ad1split = ad1.split(" ")
ad2split = ad2.split(" ")
print ' '.join( ad1split[: len(ad1split)-3 ] ) # 123 Northwest Johnson
print ' '.join( ad2split[: len(ad1split)-3 ] ) # PO Box 3
This however only works if all addresses have the same format.
I have been trying to extract transport node names and location coordinate strings from a webpage scrape (that I have permission to scrape). The names and locations are in cdata blocks of javascript. See here: http://pastebin.com/6Vtup2dE

I've written plenty of regex in my time but I've never had problems like this. I am trying (believe it or not) to hide everything up to and including "new simpleInfo(' and then grab the string up to the next "'" but I can't work it out. help!
Try this:
re.findall(r"(?:\(new\sMicrosoft\.Maps\.Location\(([^)]+)\).+?new\ssimpleInfo\(\\?'(.+?)\\?')", test_str)
This regex find all occurences whether there is \'Buchanan Bus Station\' or 'Buchanan Bus Station'.
Here is the demo
(?:\(new\sMicrosoft\.Maps\.Location\()(.+?(?=\)\,))(?:.+?).*?new\ssimpleInfo\(\\'([^'\\]+)
Try this.This should give you what you want.
import re
p = re.compile(ur'(?:\(new\sMicrosoft\.Maps\.Location\()(.+?(?=\)\,))(?:.+?).*?new\ssimpleInfo\(\\\'([^\'\\]+)')
