Ubuntu 'bash: python: command not found' Error: Solution & Explanation

This error message indicates that the Ubuntu terminal cannot recognize the 'Python' command. This usually means either Python isn't installed on your system, or the 'PATH' environment variable hasn't been configured correctly.

To fix this, follow these steps:

1. Install Python

If Python isn't installed, use this command to install it:

sudo apt-get update
sudo apt-get install python

2. Set the PATH Environment Variable

If Python is already installed, you might need to add the Python executable path to the 'PATH' environment variable. Open your '~/.bashrc' file (using a text editor like 'nano') and add this line:

export PATH=$PATH:/usr/bin/python

3. Apply Changes

After modifying the '~/.bashrc' file, you need to apply the changes. Run this command:

source ~/.bashrc

Now try running the 'python' command again. It should be recognized by the terminal.

If you still encounter issues, double-check the installation process and verify the Python executable path (usually '/usr/bin/python').
