There are many programming interfaces to choose from. Any will work. We use the PyCharm Community interface in this manual. After installation of Python and the interface, all programs will run the same.
Because of package dependencies we must first install Visual Studio Community 2022 by Microsoft. You must sign up for a free Microsoft account. You probably already have one if you have a Hotmail account or use Microsoft Office products.
2.0.1 Before we begin the Visual Studio Community 2022 install we will update the Windows setuptools. Type cmd in the Search box. At the Administrator command prompt in Windows run the following command.
pip install --upgrade setuptools

import matplotlib.pyplot as plt
import numpy as np
days = [1,3,5,6,8,]
temp = [37,34,37,35,34]

2.2.0 The PyCharm screen is divided into three main parts. The left hand side is the Project Files management pane. The right hand side is the code pane, and at the bottom is the results pane. It is important to know where your cursor is because it determines the active pane. Be sure the code pane is active when running the code. Be sure the results pane is active when entering input values. We must activate the upper left pane with the cursor to use File->New->Python File.
