ModuleNotFoundError: No module named 'pytz'

The error "ModuleNotFoundError: No module named 'pytz'" occurs when you are trying to use the pytz library in your Python program, but Python cannot find the library because it is not installed.

To fix this error, you can install the pytz library using pip, which is the package installer for Python. Open a terminal or command prompt and type the following command:

pip install pytz

This will download and install the pytz library and all its dependencies. Once the installation is complete, you should be able to import pytz in your Python program without encountering the ModuleNotFoundError.

If you are using a virtual environment, make sure you activate the environment before installing the pytz library.
