3.4.1. Importing Modules into Python#

To use packages or libraries in Python, you will need to import them at the start of your Python code:

import matplotlib.pytplot as plt
import numpy as np
import pandas as pd
import h5py

Note that for the matplotlib library we can also import it using the following synthax from … import as exemplified below.

from matplotlib import pyplot as plt
