如何在python中的点（。）之后更改大写单词

Question

我想找到一种方法，如何更改python中句点（。）之后的第一个字母？

示例：

hello world. this is test. please help 

我想要的结果是：

Hello world. This is test. Please help.

我试过这样，但它不起作用：

text = 'hello world. this is test. please help'
print text.capitalize()

Answer 1

试试这个：

sentence = "hello world. this is test. please help."
print(". ".join(i.capitalize() for i in sentence.split(". ")))
