compare lines in a file with a string

Question

I\'m trying to see if my list already has a specific user in it. I should get \"match found\" printed out but I don\'t. I thought the problem was in my php-file so i created

Answer 1

If you create the following file xx.in:

test line 1
test line 2

and run the following Python program, you'll see exactly why the match is failing:

file = open('xx.in')
for line in file:
    print '[%s]' % (line)

The output is:

[test line 1
]
[test line 2
]

showing that the newline characters are being left on the line when they're read in. If you want them stripped off, you can use:

line = line.rstrip('\n')

This will remove all newline characters from the end of the string and, unlike strip(), will not affect any other whitespace characters at either the start or end.
