Alex had a great time learning about the datetime module in Python and was eager to explore another useful module – the math module. The math module provides access to mathematical functions and constants in Python. With the math module, Alex could perform advanced mathematical operations that were not available with basic arithmetic operators.
Alex started by importing the math module.
import math
He then used the math.sqrt() function to calculate the square root of a number.
num = 25
square_root = math.sqrt(num)
print("The square root of", num, "is:", square_root)
The output was:
The square root of 25 is: 5.0
Next, Alex used the math.pi constant to calculate the circumference of a circle with a radius of 5.
radius = 5
circumference = 2 * math.pi * radius
print("The circumference of a circle with a radius of", radius, "is:", circumference)
The output was:
The circumference of a circle with a radius of 5 is: 31.41592653589793
Alex also used the math.pow() function to raise a number to a power.
num = 2 power = 3 result = math.pow(num, power) print(num, "raised to the power of", power, "is:", result)
The output was:
2 raised to the power of 3 is: 8.0
Alex was amazed at the power and flexibility of the math module. He realized that with the math module, he could perform complex mathematical calculations with ease. He also learned that the math module had many other useful functions and constants, such as trigonometric functions, logarithmic functions, and mathematical constants, that he could use in his future projects.
