No module named 'holidays'

The error message "No module named 'holidays'" means that the Python interpreter is unable to find the module named "holidays" that your code is trying to import. This can occur for a few reasons:

1. The module is not installed: You may not have installed the "holidays" module using pip or another package manager.

2. The module is installed in the wrong location: The "holidays" module may be installed in a location that is not on Python's module search path.

To resolve this issue, you can try the following steps:

1. Install the "holidays" module using pip: Open a terminal or command prompt and enter the command "pip install holidays". This should install the latest version of the module.

2. Check the installation location: If the module is already installed, you can check its installation location by running the command "pip show holidays". Make sure that the location is included in Python's module search path.

3. Check the module name spelling: Double-check that you have spelled the module name correctly in your code and in the installation command.
