Is there any way to convert an entire user inputed string from uppercase, or even part uppercase to lowercase? eg. Kilometers --> kilometers. I am writing a program that doesn't work when any sort of uppercase word is inputed and it would take LOTS more lines of code to make it work with uppercase. (I'm kind of new to programming so this may seem like a stupid question). THANKS

If you use an IDE such as Pycharm, you can learn the methods and functions of languages faster with autocomplete. Python is great, too, because the methods are all logically named, so you can guess and usually you're right. –  notbad.jpeg May 4 at 18:02

s = "Kilometer"
print(s.lower())

You can do what Peter said, or if you want the user to input something you could do this:

raw_input('Type Something').lower()

It will then automatically convert the thing they typed into lowercase. :)

Note: raw_input was renamed to input in Python 3.x and above.

also, you can overwrite some variables:

s = input('UPPER CASE')
lower = s.lower()

if you use like this:

s = "Kilometer"
print(s.lower())     - kilometer
print(s)             - Kilometer

it will work just when call.

This doesn't work for non-english words in utf-8. In this case decode('utf-8') can help.

>>> s='Километр'
>>> print s.lower()
Километр
>>> print s.decode('utf-8').lower()
километр
