I have problem with comparing string from file with string I entered in the program, I should get that they are equal but no matter if i use decode('utf-8') I get that they are not equal. Here's the code:
final = open("info", 'r')
exported = open("final",'w')
lines = final.readlines()
for line in lines:
if line == "Wykształcenie i praca": #error
print "ok"
and how I save file that I try read:
comm_p = bs4.BeautifulSoup(comm)
comm_f.write(comm_p.prettify().encode('utf-8'))
for string in comm_p.strings:
#print repr(string).encode('utf-8')
save = string.encode('utf-8') # there is how i save
info.write(save)
info.write("\n")
info.close()
and at the top of file I have # -- coding: utf-8 --
Any ideas?

This should do what you need:
# -- coding: utf-8 --
import io
with io.open('info', encoding='utf-8') as final:
lines = final.readlines()
for line in lines:
if line.strip() == u"Wykształcenie i praca": #error
print "ok"
You need to open the file with the right encoding, and since your string is not ascii, you should mark it as unicode.

First, you need some basic knowledge about encodings. This is a good place to start. You don't have to read everything right now, but try to get as far as you can.
About your current problem:
You're reading a UTF-8 encoded file (probably), but you're reading it as an ASCII file. open() doesn't do any conversion for you.
So what you need to do (at least):
- use
codecs.open("info", "r", encoding="utf-8")to read the file - use Unicode strings for comparison:
if line.rstrip() == u"Wykształcenie i praca":

It is likely the difference is in a '\n' character
readlines doesn't strip '\n' - see Best method for reading newline delimited files in Python and discarding the newlines?
In general it is not a good idea to put a Unicode string in your code, it would be a good idea to read it from a resource file

use unicode for string comparision
>>> s = u'Wykształcenie i praca'
>>> s == u'Wykształcenie i praca'
True
>>>
when it comes to string unicode is the smartest move :)
print "%r %r" % (line, "Wykształcenie i praca")right before the comparison line and tell us what it says
