Convert UPPERCASE string to sentence case in Python

问题:

How does one convert an uppercase string to proper sentence-case? Example string:

"OPERATOR FAIL TO PROPERLY REMOVE SOLID WASTE" 

Using titlecase(str) gives me:

"Operator Fail to Properly Remove Solid Waste" 

What I need is:

"Operator fail to properly remove solid waste" 

Is there an easy way to do this?

回答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' 

回答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('. '))
