Calling Python file with command line arguments from another python file

Question

Currently my python code is called from command line as follows:

C:\project-master>python myFile.py --plugin TestPlugin\migration -f "C:/Form1/All_2020-01-01.xsd"

Where myFile.py code needs commandline arguments:

--plugin TestPlugin\migration
-f "C:/Form1/All_2020-01-01.xsd"

I have created a new python file called: Test.py. From Test.py file, how can I make a call to myFile.py along with the required arguments. For example-

class Workflow:

    def Process(self):
        # How to make a call for below commandline from here: 
        # myFile.py --plugin TestPlugin\migration -f "C:/Form1/All_2020-01-01.xsd"

A = Workflow()
A.Process()

Well you haven't shown the code you're trying to call, so not really. But any decent tutorial will cover importing code and calling classes and functions. — jonrsharpe

Python subprocess module is your friend on this one.

You can use the run() function of the subprocess module. Your execution command is given as a list of strings as the first arugment in run()

So in your case it should look like this:

import subprocess

subprocess.run(["python", "myFile.py", "--plugin", "TestPlugin\migration", "-f", "C:/Form1/All_2020-01-01.xsd"], shell=False)

You can put that line into your Process() method.

Also have a look in the documentation if you want to catch the output e.g.
