title: running python scripts with command line arguments - a step-by-step tutorial
introduction:
python scripts often need to receive input values during execution. command line arguments provide a convenient way to pass these inputs. this tutorial will guide you through the process of running python scripts with command line arguments, using practical examples.
step 1: create a python script:
begin by creating a simple python script that accepts command line arguments. for example, let's create a script named script_with_args.py:
step 2: understanding sys.argv:
in the script above, sys.argv is a list in python, which contains the command-line arguments passed to the script. sys.argv[0] is the script name, and subsequent elements (sys.argv[1:]) are the actual arguments.
step 3: running the script:
open a terminal or command prompt in the directory where the script is located. to run the script with arguments, use the following syntax:
replace arg1, arg2, and arg3 with the desired values. the script will receive these arguments and print them.
example:
output:
step 4: parsing arguments with argparse (optional):
for more complex scenarios, consider using the argparse module for better argument parsing and handling. modify the script as follows:
now, run the script with:
conclusion:
in this tutorial, we've covered the basics of running python scripts with command line arguments. whether using sys.argv for simple cases or argparse for more advanced scenarios, understanding how to pass and handle arguments enhances the versatility of your python scripts.
