如何从python文件运行powerShell脚本

Question

I couldn't find much information on this unfortunately, but I wish to run a powerShell script from a python file I've written. I want the user to actually see the powerShell script being run and the user can enter inputs that the powerShell script requires from python. I am using pyCharm as an IDE.

When I run the script to call this powerShell script, it gives me this error:

File "C:\TestAutomation\eFuse\eFuse.ps1", line 19
SyntaxError: Non-ASCII character '\xc2' in file C:\Test\eK\eK.ps1 on line 19, but no encoding declared; see http://python.org/dev/peps/pep-0263/ for details

Here is the relevant part of the code:

        elif switch_result == "eTool":
            subprocess.call(['python', 'C:\\TestAutomation\\eFuse\\eFuse.ps1'], stdout=sys.stdout)

This elif statement is a part of other if/elif statements that run other python files using the subproccess module, but for some reason I can't get this powerShell file to be run. Any advice is appreciated. Thank you

Answer 1

First, you should already know .py file's interpreter is python.exe

So, it's easy to understand .ps1 file's interpreter is powershell.exe , not python.exe

I just copy & paste from yours, your code should look like following,

subprocess.call('powershell.exe -File "C:\\TestAutomation\\eFuse\\eFuse.ps1"', stdout=sys.stdout)

Details about powershell.exe -?

You can do following for provide input from user to PS (powershell) script from python :

1) Create parameterised powershell script

2) Take input in python and set it as PS script parameter.

3) run/execute the script with given params.

Here is the sample to run powershell script from python with param. Its a python code :

* Hope you have the PS script with parameters.

import subprocess

params = ['param1', 'param2']  # POWERSHELL SCRIPT PARAMETERS ( optional )
script_path = "C:\\PowershellScripts\\test.PS1"  # POWERSHELL SCRIPT PATH
commandline_options = ["Powershell.exe", '-ExecutionPolicy', 'Unrestricted', script_path]  # INITIALIZING COMMAND
for param in params:  # FOREACH LOOP OF PARAMETERS
    commandline_options.append(param)  # ADDING SCRIPT PARAMETERS TO THE COMMAND

result = subprocess.run(commandline_options, stdout = subprocess.PIPE, stderr = subprocess.PIPE, universal_newlines = True)  # RUN THE SCRIPT USING SUBPROCESS WITH PARAMS

print(result.returncode)  # PRINT THE RETURN CODE FROM POWERSHELL SCRIPT
print(result.stdout)  # PRINT THE STANDARD OUTPUT FROM POWERSHELL SCRIPT
print(result.stderr)  # PRINT THE STANDARD ERROR FROM POWERSHELL SCRIPT

You can see the output of python if it exist ( if there is no error in powershell script. you will not get any output from last line )
