Certainly! Passing parameters to a Python script that will be run using a Bash script is a common task. This tutorial will guide you through the process, providing code examples along the way.
Let's start by creating a simple Python script that accepts parameters. Create a file named myscript.py with the following content:
This script uses the sys.argv list to access the command-line arguments passed to the script.
Now, create a Bash script (e.g., run_script.sh) to execute the Python script with parameters. Open a new file and add the following content:
In this example, we've defined two parameters (param1 and param2) in the Bash script and passed them to the Python script using the python3 command.
Before running the Bash script, make it executable. Open a terminal and navigate to the directory containing your Bash script (run_script.sh). Run the following command:
This command grants execute permissions to the Bash script.
Now, you can run the Bash script to execute the Python script with parameters. In the terminal, navigate to the script's directory and run:
You should see the output from the Python script, displaying the total number of arguments, the script name, and the provided arguments.
That's it! You've successfully passed parameters to a Python script using a Bash script. You can modify the Bash script to pass different parameters as needed for your specific use case.
