How Can I Pass Arguments to a Python Script When Running it from Another Script?

Run a Python Script from Another Script with Arguments

In Python, there are several ways to execute one script from another. One common technique is to use the os.system function, which allows you to pass arguments from the calling script to the invoked script.

Suppose we have two Python scripts: script1.py and script2.py. script1.py needs to iterate through a list of values and pass them as arguments to script2.py, similar to how you would use the command line.

To accomplish this, use the following code in script1.py:

<code class="python">import os

# Define the list of values to iterate through
values = [0, 1, 2, 3]

# Iterate through the values and call script2.py with each value as an argument
for value in values:
    os.system(f"script2.py {value}")</code>

Here, we import the os module and define the values list. Then, we enter a loop where we execute script2.py with each value as a separate argument.

Note that os.system is designed to run a command as a subprocess in the operating system. In this case, it will invoke script2.py as a separate process and pass the provided argument to it.

Within script2.py, you can access the arguments passed from script1.py using the sys.argv variable, which contains a list of strings representing the command-line arguments.

This method allows you to easily pass arguments between Python scripts and execute them within different execution contexts.
