how to import 'matplotlib'

To import matplotlib, you will first need to install it. You can install the package using pip, the Python package manager.

To install matplotlib, open a terminal and enter the following command:

pip install matplotlib

This will install matplotlib and its dependencies. Once the installation is complete, you should be able to import matplotlib in your Python code using:

import matplotlib

If you are using a version of Python that is earlier than 3.4, you may need to use pip3 instead of pip to install the package.

pip3 install matplotlib
