Question

I read this:
Stripping everything but alphanumeric chars from a string in Python

and this:
Python: Strip everything but spaces and alphanumeric

Didn’t quite understand but I tried a bit on my own code, which now looks like this:

import re

decrypt = str(open("crypt.txt"))

crypt = re.sub(r'([^\s\w]|_)+', '', decrypt)

print(crypt)

When I run the script It comes back with this answer:
C:\Users\Adrian\Desktop\python>python tick.py
ioTextIOWrapper namecrypttxt moder encodingcp1252

I am trying to get away all the extra code from the document and just keep numbers and letter, inside the document the following text can be found: http://pastebin.com/Hj3SjhxC

I am trying to solve the assignment here:
http://www.pythonchallenge.com/pc/def/ocr.html

Anyone knows what “ioTextIOWrapper namecrypttxt moder encodingcp1252” means?
And how should I format the code to properly strip it from everything except letter and numbers?

Sincerely

You could just search for the alphanumeric chars instead. Like this:

print ''.join(re.findall('[A-Za-z]', decrypt))

And you also want:

decrypt = open("crypt.txt").read()
