Matrix determinant (det) in SciPy - Mini Project: Build & Apply

Calculate Matrix Determinant Using SciPy

📖 Scenario: You work as a data analyst and need to find the determinant of a matrix to understand its properties. The determinant helps in solving systems of linear equations and checking if a matrix is invertible.

🎯 Goal: Build a Python program that creates a matrix, sets up the necessary configuration, calculates the determinant using SciPy, and prints the result.

📋 What You'll Learn

Create a 3x3 matrix with exact values

Import the required function from SciPy

💡 Why This Matters

🌍 Real World

Determinants are used in engineering and data science to check if systems of equations have unique solutions and to analyze matrix properties.

💼 Career

Knowing how to calculate determinants is useful for roles involving linear algebra, such as data scientists, machine learning engineers, and researchers.

1

Create the matrix

Create a variable called matrix and assign it a 3x3 list of lists with these exact values: [[4, 2, 3], [3, 1, 5], [1, 0, 2]].

SciPy

# Create the matrix variable with the given values
# Your code here

Need a hint?

Use a list of lists to represent the matrix rows and columns exactly as shown.

2

Import the determinant function

Import the det function from the scipy.linalg module.

SciPy

matrix = [[4, 2, 3], [3, 1, 5], [1, 0, 2]]
# Import det from scipy.linalg
# Your code here

Need a hint?

Use the exact import statement: from scipy.linalg import det.

3

Calculate the determinant

Create a variable called determinant and assign it the result of calling det(matrix).

SciPy

matrix = [[4, 2, 3], [3, 1, 5], [1, 0, 2]]
from scipy.linalg import det
# Calculate the determinant of matrix
# Your code here

Need a hint?

Call det(matrix) and store the result in determinant.

4

Print the determinant

Print the value of the variable determinant.

SciPy

matrix = [[4, 2, 3], [3, 1, 5], [1, 0, 2]]
from scipy.linalg import det
determinant = det(matrix)
# Print the determinant
# Your code here

Need a hint?

Use print(determinant) to show the result.
