Write a Shell script that runs a Python script.The Python file name will be saved in the environment variable $PYFILE

To write a shell script that runs a Python script, follow these steps:

1. Open a text editor and create a new file.
2. Start the script by adding a shebang line at the top, which specifies the interpreter to use. For example, #!/bin/bash for a Bash script.
3. Declare a variable to store the Python file name. You can use the environment variable $PYFILE by accessing it with $PYFILE.
4. Use the python command followed by the variable to run the Python script. For example, python $PYFILE.
5. Save the file with a .sh extension, such as run_python_script.sh.
6. Make the script executable by running the command chmod +x run_python_script.sh.
7. To run the script, use the command ./run_python_script.sh.

Make sure that the Python script file specified in the $PYFILE environment variable exists in the same directory as the shell script, or provide the full path to the Python script file.
