Problem 1: Compare Linear Regression, Ridge, and Lasso Coefficients

Problem Description

Write a Python program that trains standard Linear Regression, Ridge, and Lasso models on the same dataset, and prints their learned coefficients side by side.

Input

A dataset with several numeric features.

Output

The coefficients from all three models.

Constraints

• At least 6 data points with 3+ features.

Example Input

text
(A dataset with 4 features across 6 rows)

Example Output

text
Linear: [...]
Ridge: [...]
Lasso: [...]
