Python: Last character of user input

Question

I was just wondering how I could find out what the last character of the user input was using Python. I need to know whether it was an S or not. Thanks in advance.....

Please edit your question to include how you are gathering users input. Are you using raw_input() ? — Bryan, Aug 11 '13 at 03:34
what @falsetru said, or user_input[-1] if the input is a string (it should be) — Aaron, Aug 11 '13 at 03:35

You can use the built-in function str.endswith():

if raw_input('Enter a word: ').endswith('s'):
    do_stuff()

Or, you can use Python's Slice Notation:

if raw_input('Enter a word: ')[-1:] == 's': # Or you can use [-1]
    do_stuff()

@user2357112: using a slice prevents an IndexError in case of an empty string. – DSM Aug 11 '13 at 03:38

Use str.endswith:

>>> "fooS".endswith('S')
True
>>> "foob".endswith('S')
False

help on str.endswith:

>>> print str.endswith.__doc__
S.endswith(suffix[, start[, end]]) -> bool

Return True if S ends with the specified suffix, False otherwise.
With optional start, test S beginning at that position.
With optional end, stop comparing S at that position.
suffix can also be a tuple of strings to try.

Strings can be treated like lists of characters, and to get the last item of a list you can use -1, so after you convert the string to lowercase (just in case you have an uppercase s), your code will look like:

if (user_input.lower()[-1] == 's'):
    #Do Stuff
