尝试将多行字符串大写，但不起作用。有什么想法吗？
Trying to capitalize multiline string, but not working. any thoughts?
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。
str.capitalize is documented 只将整个字符串的第一个字符大写，其余小写：
str.capitalize()
Return a copy of the string with its first character capitalized and the rest lowercased.
如果要将每个单词的第一个字母大写（将其余字母小写），use .title(); if you want every character to be uppercase, use .upper()。
来自official documentation 关于capitalize():
Return a copy of the string with its first character capitalized and
the rest lowercased.
您正在寻找的方法是title()，它将每个单词大写。这是来自 the documentation 的描述：
Return a titlecased version of the string where words start with an uppercase character and the remaining characters are lowercase.
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.'
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())
