ImportError: No module named 'pandas'

The code attempted to import the 'pandas' module, but Python could not find it. This usually happens when the library is not installed or the environment is not set up correctly.

The root cause is that the 'pandas' library is not included in the Python environment you are using. This can occur if you are using a virtual environment that does not have 'pandas' installed or if 'pandas' was never installed in the global environment.

To fix this, you need to install the 'pandas' library. You can do this using pip, which is the package installer for Python. Run the command 'pip install pandas' in your terminal or command prompt.
