Question

例如，經歷了這個過程的字符串：

Hello, WORLD, McGisty, you are my HERO THAT I am.

Hello, World, McGisty, you are my Hero That I am.

Answer 1

>>> x = 'Hello, WORLD, McGisty, you are my HERO THAT I am.'
>>> m = ' '.join(e.capitalize() if e.isupper() else e for e in x.split())
>>> m
'Hello, World, McGisty, you are my Hero That I am.'

Answer 2

使用re模塊：

>>> import re
>>> x = 'Hello, WORLD, McGisty, you are my HERO THAT I am.'
>>> re.sub(r'[A-Z]+', lambda s: s.group().capitalize(), x)
'Hello, World, McGisty, you are my Hero That I am.'
