Convert UPPERCASE string to sentence case in Python

Solution 1:

Let's use an even more appropriate function for this: string.capitalize

>>> s="OPERATOR FAIL TO PROPERLY REMOVE SOLID WASTE"
>>> s.capitalize()
'Operator fail to properly remove solid waste'

Solution 2:

This will work for any sentence, or any paragraph. Note that the sentence must end with a . or it won't be treated as a new sentence. (Stealing .capitalize() which is the better method, hats off to brianpck for that)

a = 'hello. i am a sentence.'
a = '. '.join(i.capitalize() for i in a.split('. '))
