如何在 Windows 命令行中使用参数运行 Python 脚本 [英] How do I run Python script using arguments in windows command line

问题描述

这是我的 python hello.py 脚本:

This is my python hello.py script:

def hello(a,b):
    print "hello and that's your sum:"
    sum=a+b
    print sum
    import sys

if __name__ == "__main__":
    hello(sys.argv[2])

问题是在windows命令行提示符下无法运行，我用了这个命令:

The problem is that it can't be run from the windows command line prompt, I used this command:

C:\Python27>hello 1 1

但不幸的是它没有用，有人可以帮忙吗?

But it didn't work unfortunately, may somebody please help?

推荐答案

• import sys 出 hello 函数.
• 参数应转换为 int.
• 包含 ' 的字符串文字应该被转义或者应该被 " 包围.
• 您是否使用 python hello.py <some-number> 调用了该程序? 在命令行中?
• import sys out of hello function.
• arguments should be converted to int.
• String literal that contain ' should be escaped or should be surrouned by ".
• Did you invoke the program with python hello.py <some-number> <some-number> in command line?

import sys

def hello(a,b):
    print "hello and that's your sum:", a + b

if __name__ == "__main__":
    a = int(sys.argv[1])
    b = int(sys.argv[2])
    hello(a, b)
