Why am i getting 'python is not recognized' after installation?

After installing Python on some systems, the PATH might not be set correctly, causing command prompt or terminal to not recognize the `python` command.

Example:

'python' is not recognized as an internal or external command, operable program or batch file.

Solution:

1. Ensure Python's installation directory is added to the system's PATH.
2. On Windows, during installation, check the 'Add Python to PATH' option.
3. On Linux/Mac, modify the ~/.bashrc or ~/.bash_profile file.
