用户输入和命令行参数[关闭]

如何拥有可以接受用户输入的 Python 脚本？如果从命令行运行，如何让它读取参数？

要读取用户输入，您可以尝试the cmd module https://docs.python.org/dev/library/cmd.html用于轻松创建迷你命令行解释器（带有帮助文本和自动完成功能）以及raw_input https://docs.python.org/2/library/functions.html#raw_input (input https://docs.python.org/dev/library/functions.html#input对于 Python 3+）用于读取用户的一行文本。

text = raw_input("prompt")  # Python 2
text = input("prompt")  # Python 3

命令行输入位于sys.argv。在你的脚本中尝试一下：

import sys
print (sys.argv)

There are two modules for parsing command line options: optparse https://docs.python.org/dev/library/optparse.html (deprecated since Python 2.7, use argparse https://docs.python.org/dev/library/argparse.html instead) and getopt https://docs.python.org/dev/library/getopt.html. If you just want to input files to your script, behold the power of fileinput https://docs.python.org/dev/library/fileinput.html.

The Python 库参考 https://docs.python.org/dev/library/是你的朋友。
