Mathematical constants (pi, e, golden ratio) in SciPy - Mini Project: Build & Apply

Using Mathematical Constants with SciPy

📖 Scenario: You are working on a simple science project where you need to use important mathematical constants like pi, e, and the golden ratio. These constants help in many calculations in science and nature.

🎯 Goal: You will create a Python program that stores these constants using SciPy and then prints them out. This will help you understand how to use built-in constants in Python for your calculations.

📋 What You'll Learn

Use the scipy.constants module to access constants

Create variables for pi, e, and golden_ratio with exact values from SciPy

Print the values of these constants

💡 Why This Matters

🌍 Real World

Mathematical constants like pi and e are used in physics, engineering, and computer science to solve real problems involving circles, growth, and patterns.

💼 Career

Knowing how to use built-in constants helps data scientists and engineers write accurate and efficient code for scientific calculations.

1

Import SciPy constants and create variables

Write code to import scipy.constants as const. Then create three variables called pi, e, and golden_ratio and assign them the values const.pi, const.e, and const.golden_ratio respectively.

SciPy

# Import scipy.constants as const
# Create variables pi, e, and golden_ratio with values from const
# Your code here

Need a hint?

Use import scipy.constants as const to import the constants module. Then assign pi = const.pi, e = const.e, and golden_ratio = const.golden_ratio.

2

Create a list of constants

Create a list called constants_list that contains the variables pi, e, and golden_ratio in that order.

SciPy

import scipy.constants as const

pi = const.pi
e = const.e
golden_ratio = const.golden_ratio

# Create a list called constants_list with pi, e, and golden_ratio
# Your code here

Need a hint?

Use square brackets to create a list: constants_list = [pi, e, golden_ratio].

3

Create a dictionary with constant names and values

Create a dictionary called constants_dict with keys 'pi', 'e', and 'golden_ratio' and their corresponding values from the variables pi, e, and golden_ratio.

SciPy

import scipy.constants as const

pi = const.pi
e = const.e
golden_ratio = const.golden_ratio

constants_list = [pi, e, golden_ratio]

# Create a dictionary constants_dict with keys 'pi', 'e', 'golden_ratio' and their values
# Your code here

Need a hint?

Create a dictionary with curly braces and key-value pairs like {'pi': pi, 'e': e, 'golden_ratio': golden_ratio}.

4

Print the constants dictionary

Write a print statement to display the constants_dict dictionary.

SciPy

import scipy.constants as const

pi = const.pi
e = const.e
golden_ratio = const.golden_ratio

constants_list = [pi, e, golden_ratio]

constants_dict = {'pi': pi, 'e': e, 'golden_ratio': golden_ratio}

# Print the constants_dict dictionary
# Your code here

Need a hint?

Use print(constants_dict) to show the dictionary on the screen.
