How Do I Access Command Line Arguments in Python?

Accessing Command Line Arguments in Python

Acquiring command line arguments is a crucial aspect when executing Python scripts. This allows you to pass values from the console during execution, enabling dynamic configurations or user input.

Solution:

To retrieve command line arguments in Python, utilize the sys module. Its argv attribute holds a list of strings representing the arguments passed during script invocation.

The following steps guide you through the process:

1. Import the sys module.
2. Access the sys.argv list.
3. Each element in the list corresponds to one command line argument.

Example:

Consider the following code that demonstrates argument access:

import sys

print(sys.argv)

When you run this script with the command $ python myfile.py var1 var2 var3, the output in the Python console will resemble:

['myfile.py', 'var1', 'var2', 'var3']

The script's name is stored as the first element in the list (myfile.py), followed by the specified arguments.
