/bin/sh: python: command not found

This error message indicates that the system is unable to find the Python interpreter.

There could be several reasons for this error, including:

1. Python is not installed on the system
2. The PATH environment variable is not set correctly
3. The Python executable is not in the PATH

To resolve this issue, you can try the following steps:

1. Check if Python is installed on the system by running the following command in the terminal:

$ python --version

If Python is not installed, you can download and install it from the official Python website.

2. Check if the PATH environment variable is set correctly by running the following command in the terminal:

$ echo $PATH

If the Python executable is not in the PATH, you can add it by editing the PATH variable in the ~/.bashrc or ~/.bash_profile file.

3. If you have installed Python in a non-standard location, you can specify the path to the Python interpreter in the shell script by adding the following line at the top of the script:

#!/usr/bin/env python

This will tell the system to use the Python interpreter located at the specified path.
