How do I install dotenv in Python?

The standard way to install dotenv is by running `python -m pip install python-dotenv`. If you are using Anaconda, use `conda install -c conda-forge python-dotenv`.

Why causes the 'No module named dotenv' error?

This error occurs when the python interpreter cannot locate the `dotenv` package. It is often caused by missing installation or environment mismatch (e.g. installing in global but running in venv).
