python - 无法从批处理文件执行 Python 脚本

Question

我试图从命令行运行 Python 程序，所以我创建了一个批处理文件，如下所示:

@py.exe C:\MyPythonScripts\program.py%*
@pause

该脚本应该打印一条简单的消息，但是当我在 Windows 运行程序中键入“程序”时，cmd 会出现一秒钟然后自行关闭。我做错了什么？

这是代码:

#!python3

def printPicnic(itemsDict,leftWidth,rightWidth):
    print('PICNIC ITEMS'.center(leftWidth + rightWidth,'-'))
    for k,v in itemsDict.items():
        print(k.ljust(leftWidth,'.') + str(v).rjust(rightWidth))

picnicItems = {'sandwiches':4, 'apples': 12, 'cups': 4, 'cookies':8000}
printPicnic(picnicItems,12,5)
printPicnic(picnicItems,20,6)

这是我的 PATH 变量:

Answer 1

关于您的批处理文件，我建议执行以下更改:

您在 path 和 %* 之间缺少一个空格，还要将 path 括在引号中以防止它 当路径中有空格时中断

@echo off
py.exe "C:\MyPythonScripts\program.py" %1 %2 %3 %4 %5 %6 %7 %8 %9
pause
