The Ultimate Guide to Python Programming With Python 3.10 - Decorator Function

The video tutorial explains how to use a decorator function in Python to enhance a log function. It begins by introducing the log function, which prints a value. The tutorial then demonstrates how to decorate this function using a 'fence' decorator, which adds plus signs around the output. The process involves using the decorator syntax with the '@' symbol. The tutorial also includes a test of the decorated function in Python's interactive mode, showing the output with the added decorations. Finally, it delves into the workings of decorator functions, explaining the concept of a function within a function and how it modifies the behavior of the original function.
