尝试将多行字符串大写，但不起作用。有什么想法吗？

Question

text = '''felt happy because I saw the others were happy 
 and because I knew I should feel happy, 
 but I wasn’t really happy.'''

print(text.capitalize())

只有第一个单词大写。

Answer 1

来自official documentation关于capitalize()：

返回第一个字符大写的字符串副本 其余小写。

您正在寻找的方法是title()，它将大写每个单词。以下是来自the documentation的描述：

返回字符串的标题版本，其中单词以大写字符开头，其余字符为小写。

结果如下：

>>> text = '''felt happy because I saw the others were happy and because I knew I should feel happy, but I wasn’t really happy.'''
>>> print(text.title())

'Felt Happy Because I Saw The Others Were Happy And Because I Knew I Should Feel Happy, But I Wasn’T Really Happy.'

Answer 2

str.capitalize is documented 只将整个字符串的第一个字符大写，其余的小写：

str.capitalize()

返回第一个字符大写，其余小写的字符串副本。

如果要将每个单词的首字母大写（其余字母小写），use .title()；如果你希望每个字符都是大写，use .upper()。
