Python In Practice - 15 Projects to Master Python - Asking the Model to Make Predictions - Machine Learning with Python

The video tutorial explains how to create a machine learning model using linear regression in Python. It covers the process of initializing the model, training it with input and output data using the fit method, and making predictions with new data. The tutorial also discusses evaluating the model's performance by splitting data into training and testing sets to compare predicted and actual values.
