无法从批处理文件执行Python脚本

Question

I'm trying to run a Python program from the command line so I created a batch file like so:

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

The script should print a simple message, but when I type "program" in the Windows Run program cmd appears for a second and closes itself. What am I doing wrong?.

This is the code:

#!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)

This is my PATH variable:

> Files\Intel\Shared
> Files\cpp\bin\Intel64;C:\ProgramData\Oracle\Java\javapath;C:\Program

Answer 1

Regarding your batch file, I would suggest perform these changes:

You were missing a space inbetween the path and the %* , also enclose the path in quotes to prevent it from breaking when spaces are in the path

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

Answer 2

The problem in your batch file is a missing SPACE :

@rem               THERE MUST BE A SPACE:
@rem                                 |
@rem                                 V
@py.exe C:\MyPythonScripts\program.py %*
@pause

In addition, I strongly recommend to put quotation marks around paths in order to avoid trouble with white-spaces and other spacial characters.

Answer 3

You can do it using the following method :

@ECHO OFF
setlocal
set PYTHONPATH=C:\Python35 (you version of python)
C:\MyPythonScripts\program.py  %1<-- (you you have arg)  
endlocal
