Python In Practice - 15 Projects to Master Python - filter( )

The video tutorial explains how to use the filter function in Python to filter elements from a list. It begins by introducing the filter function and then defines a custom function to check for even numbers. The tutorial demonstrates how to apply the filter function using this custom function and iterates over the filtered results to store them in a new list. The process is illustrated with examples, showing how even numbers are extracted from a list of random numbers.
