Which of the following regular expressions can be used to get the domain name?
I try the next code but it doesn't work, there is something that i'm doing wrong?
In the picture the another options
txt = 'I refer to https://google.com and i never refer http://www.baidu.com'
print(txt.findall(?<=https:\/\/)([A-Za-z0-9.]*))

You selected the correct regexp, you just have to quote it to use it in Python. You also need to call re.findall(), it's not a string method.
import re
txt = 'I refer to https://google.com and i never refer http://www.baidu.com'
print(re.findall(r'(?<=https:\/\/)([A-Za-z0-9.]*)', txt))

Here's a regex that'll get your URLs
http(s?)://(?:[a-z0-9](?:[a-z0-9-]{0,61}[a-z0-9])?\.)+[a-z0-9][a-z0-9-]{0,61}[a-z0-9]
It'll work for https://stackoverflow.com, http://example.com, https://example.com etc...
If you don't want the http or https just use this:
(?:[a-z0-9](?:[a-z0-9-]{0,61}[a-z0-9])?\.)+[a-z0-9][a-z0-9-]{0,61}[a-z0-9]

I have tried looking this up, but for some reason I cannot find anything about it. How do I run a script by giving the particular file directory in start()?
This works (when Test is in the same folder as the main script):
self.process.start("python3 Test.py")
This does NOT work:
self.process.start("python3 /my/path/Test.py")

Try this:
self.process.start("python3 ../my/path/Test.py") # added two periods before "/m"

Hello I am trying to scrape a website and its going fine, till the point I try to save the data into a csv via csv module writer. I traced back to the data and find out that 7 años is the string which isn't allowing the data to store properly.
I READ A LOT ON THIS TOPIC BEFORE POSTING... BUT COULDN'T GRASP THE CONCEPT.
Python is throwing some encoding error which got me to reading and I found that csv module isn't capable of unicode.
Is there any suggestion?

Try to use following solution
def sanitize_string(string):
return string.replace('\t', '')
Try to encode the string using encode function
your_variable = sanitize_string("your string")
your_variable.encode('utf8')
Hope this will help you.

I’m trying to print a string that is too long to be displayed on one line, so it automatically wraps to the next line. The problem is that I need it to all stay on one line and just go off the screen (where I can just scroll left to right to see it all).Is there a way to to disable word wrap in python IDLE
by changing somethings in configure option

Text wrapping is a function of your terminal, not python. All that python does is send a string to the terminal - think about it, when you say print "abcdef\n", there's no character in there that tells the terminal to wrap-text!
You just need to configure the environment you're coding in. There should be a pretty easily accessible 'settings' option. However, if you can't find it, then tell us what environment you're using - we might be able to help.

When I ctrl click a builtin function in my IDE I noticed I usually get sended to an init file which holds the function but it just returns the function again.. It states a vague doc string like 'original footprint unknown'
Where do I find the real functions ?
For example where is print_function

the specific example, print is defined in C, in the bltinmodule.c: specifically.
http://hg.python.org/cpython/file/3.3/Python/bltinmodule.c#l1518
More generally, functions implemented in C have no equivalent to the source file you would read in python; the C code is compiled into binary machine code, and no reference to where that bit of code might have come from is (usually) retained in the result; and even if there was, it's unlikely that you happen to have the source code installed in a place your IDE is likely to find it, unless you built it yourself, with debug symbols, and are running the C executable process in that ide's debugger.

Usually in the same directory where that file is. (Which I can't possibly know.)
