How can I use regular expressions to extract all words with at least one digit in text with Python

I am new to regular expressions and I have a text as follows. How can I use the RegEx to extract all words with at least one digit in it? Really appreciate it.
text = '''The start of the Civil War in 1861 followed by Tennessee’s secession from the Union and the lodging of
wounded Confederate soldiers on campus did not close East Tennessee University. By spring 1862 when the
trustees finally suspended operations, the majority of students had joined the military, President Joseph
Ridley had resigned, and two professors had left the university. Wounded Confederate soldiers were lodged
at university buildings after the January 1862 Battle of Mill Springs in Kentucky, known as the Battle of
Fishing Creek to the Confederacy. In the fall of 1863, Union troops forced the Confederates out of
Knoxville. On the Hill, the Union Army enclosed the three university buildings with an earthen
fortification they named Fort Byington in honor of an officer from Michigan who was killed in the defense
of Knoxville. They used the buildings for their headquarters, barracks, and a hospital for Black troops.
Despite a Confederate attempt to retake the city by siege—climaxed by a bloody, abortive attack on Fort
Sanders on November 29, 1863—the Union held and occupied Knoxville for the rest of the war. During the
battle, the Hill was hit with artillery fire from Confederate guns located in a trench at the site of
UT’s present-day Sorority Village. Campus also sustained a great deal of damage caused by the Union Army.
Troops denuded the grounds of trees, ruined the steward’s house, and destroyed the gymnasium with
misdirected cannon fire aimed at Confederate troops across the river. After the Civil War ended in 1865
and the Union Army left campus, Thomas Humes was elected university president. The university reopened in
1866 and operated for six months downtown in the Deaf and Dumb Asylum while repairs began at the damaged
campus. A petition to the federal war department for monetary compensation for campus damage done by the
Union Army undoubtedly received more favorable consideration because of Humes’s known Union loyalty
throughout the war. A Senate committee which considered the bill for damages also noted that East
Tennessee University was “particularly deserving of the favorable consideration of Congress” because it
was “the only educational institution of known loyalty…in any of the seceding states.” However in 1873,
President Ulysses S. Grant vetoed the bill that would have provided $18,500 to the university because he
felt it would set a bad precedent. The bill was redrafted specifying that the payment was compensation
for aid East Tennessee University gave to the Union during the war. On June 22, 1874, President Grant
signed the new bill and the trustees accepted the funds the same day with an agreement to release the
government from all claims. (More than a century and a half later, a buried Union trench was located in
2019 on the north side of the present-day McClung Museum with the use of ground-penetrating radar.)

You could use this pattern:
'\w*\d+\w*'
How does it work:
\w* matches 0 or more characters (but not space)
\d+ matches 1 or more digits
\w* matches 0 or more characters again
Using re and findall we get:
re.findall('\w*\d+\w*',your_text)
we get:
['1861',
'1862',
'1862',
'1863',
'29',
'1863',
'1865',
'1866',
'1873',
'18',
'500',
'22',
'1874',
'2019']

Is this what you mean?
re.findall(r"\S*\d+\S*", text)
\S any character but a space,
\d any digit,
+ one or more occurrences,
* zero or more occurrences

Can't Scrape All the UL Tag's text in python webscrape

I'm new in python webscraping and trying to scrape one of the wikipedia quote page for the practice purpose.
Link of the wikipedia Page
Code I Tried:
from bs4 import BeautifulSoup
from urllib.request import Request, urlopen
import re
req = Request('https://en.wikiquote.org/wiki/India', headers={'User-Agent':
'Mozilla/5.0'})
webpage = urlopen(req).read()
html = BeautifulSoup(webpage, 'html.parser')
quotes = html.find('ul').findAll("b")
print(quotes)
I got first quote but I want all of the quotes on the page.
Can Anyone Provide the Solution? TIA!

You have to use findAll to get all ul, then extract text from each one:
from bs4 import BeautifulSoup
from urllib.request import Request, urlopen
import re
req = Request('https://en.wikiquote.org/wiki/India', headers={'User-Agent':
'Mozilla/5.0'})
webpage = urlopen(req).read()
html = BeautifulSoup(webpage, 'html.parser')
quotes = html.findAll('ul')
for quote in quotes:
print(quote.get_text())
Result:

This also is remarkable in India, that all Indians are free, and no Indian at all is a slave. In this the Indians agree with the Lacedaemonians. Yet the Lacedaemonians have Helots for slaves, who perform the duties of slaves; but the Indians have no slaves at all, much less is any Indian a slave.

India of the ages is not dead nor has She spoken her last creative word; She lives and has still something to do for herself and the human peoples. And that which must seek now to awake is not an Anglicized oriental people, docile pupil of the West and doomed to repeat the cycle of the Occident's success and failure, but still the ancient immemorial Shakti recovering Her deepest self, lifting Her head higher toward the supreme source of light and strength and turning to discover the complete meaning and a vaster form of her Dharma.

Cleaning Wikipedia content with python

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.

For example I like to delete all sections that begin with "Reference" and "Further Reading":
== New York ==
== References ==
== Further reading ==
== California ==
== References ==
== Further reading ==
== Floria ==
== References ==
== Further reading ==
Desired Result:
== New York ==
== California ==

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.
Edit
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.

reformat unstructured text into single line after removing punctuation

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.
Plot
Example 2:
12 (0) 0 4 (0) 38 (3) 0 3 (0) 0 1 (0)
Example 3:
Franklin Township is one of the eighteen townships of Monroe County, Ohio,
United States. The 2000 census found 453 people in the township, 367 of whom
lived in the unincorporated portions of the township.
Geography
Located in the western part of the county, it borders the following townships:
The village of Stafford lies in southwestern Franklin Township.
Name and history
It is one of twenty-one Franklin Townships statewide.
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.
