python如何查找在线帮助?
在使用python时需要查一些简单命令的含义以及用法,直接help(命令)就行了。
示例:
>>>help(input) Help on built-in function input in module builtins: input(prompt=None, /) Read a string from standard input. The trailing newline is stripped. The prompt string, if given, is printed to standard output without a trailing newline before reading input. If the user hits EOF (*nix: Ctrl-D, Windows: Ctrl-Z+Return), raise EOFError. On *nix systems, readline is used if available.
