Is there a .tolower() for a string??

[Amy]

I have a string say

a = "Hello how are YOU"

I want to end up with

a = "hello how are you'

Isn't there a built in method for changing a string to lowercase?

Thanks.

"If you can't find it, it's probably in section two of the library docs."
(Hint: strings are a sequence type.)

dir("")

will give you all str attributes. The most promising is lower, so let's try:
[color=blue][color=green][color=darkred]
>>> a = "LOWER"
>>> a.lower()[/color][/color][/color]
'lower'[color=blue][color=green][color=darkred]
>>> a[/color][/color][/color]
'LOWER'

You might not have expected the last outcome. This is because the lower()
method does not change the original string but creates a new one that is
all lowercase. Strings are "immutable" , i. e. cannot be changed once they
are created. To get the desired effect, you need to "rebind" a:
[color=blue][color=green][color=darkred]
>>> a = a.lower()
>>> a[/color][/color][/color]
'lower'

S.lower() -> string

Return a copy of the string S converted to lowercase.


Read the docs!

Also, you could have said 'learn to use the help command, its more
convenient than printing __doc__':

Another command the OP might have found useful would be help(""), or
help(str) which tell you all about the string methods.
