Activity 1: Assigning Values to Variables

Solution:

1. We begin with the first step, where x has been assigned the value of 14:

   x = 14

2. Now we use the += operator to set x equal to x + 1 in the same step:

   x += 1

3. In this step, x is divided by 5, and the result is squared:

   (x/5) ** 2

   You should get the following output:

   9.0

With this activity, you have learned how to perform multiple mathematical operations on a variable. This is very common in Python. For example, in machine learning, covered in Chapter 11, Machine Learning, the input may be a matrix, X, and multiple mathematical operations will be performed on the X matrix until predictive results are obtained. Although the mathematics behind machine learning is more sophisticated, the core ideas are the same.

Activity 2: Finding a Solution Using Pythagorean Theorem in Python

Solution:

1. Open your Jupyter Notebook.
2. In this step, you...
