“for line in…” results in UnicodeDecodeError: 'utf-8' codec can't decode byte

Question

Here is my code,

for line in open(\'u.item\'):
#read each line

whenever I run this code it gives the following error:

Answer 1

If you are using Python 2 the following will the solution:

import io
for line in io.open("u.item", encoding="ISO-8859-1"):
    # do something

Because encoding parameter doesn't work with open(), you will be getting the following error:

TypeError: 'encoding' is an invalid keyword argument for this function
