我有这个：

  Warning: include(/share/HDA_DATA/Web/application/views/errors/html/error_php.php): failed to open stream: No such file or directory in /share/HDA_DATA/Web/system/core/Exceptions.php on line 269

Warning: include(): Failed opening '/share/HDA_DATA/Web/application/views/errors/html/error_php.php' for inclusion (include_path='.:/etc/config/php') in /share/HDA_DATA/Web/system/core/Exceptions.php on line 269

但它仍然没有使第一个字母大写。

Answer 1

.upper()返回一个新字符串，因为字符串是不可变数据类型。您应该将返回值设置为变量。

如果您只想将第一个字母设为大写，则可以使用.capitalize而不是.upper。

>>> word = raw_input("enter a word")
>>> word = word.capitalize()

请注意.capitalize将其余字符变为小写。如果您不希望它发生，请使用[0].upper()：

word = word[0].upper() + word[1:]

如何只将第一个字母大写？
