Print line containing “word” python

Question

I would like to print ONLY the line which contains \"Server\" in the below piece of output:

Date: Sun, 16 Dec 2012 20:07:44 GMT
Expires: -1
Cache-Control: pr         


        

Answer 1

for single_line in websiteheaders.splitlines():
    if `Server` in single_line:
        print single_line

Answer 2

Is websiteheaders really a list which is split for very line? Because if it's a string you should use:

for line in websiteheaders.splitlines():
    if "Server" in line:
        print line

Also, a good tip: I would recommend adding some print-statements on encountering this kind of problems. If you would have added something like:

else:
    print 'WRONG LINE:', line

You probably would have catched that this loop was not looping over every line but over every character.

Update

I can't wee what's wrong with your code then. This is what I get:
