Python. 1. Create a function called "additive3", where the inputs are the sets (lists) S, T, and U. If SUTUU can be determined using the additive principle, then let the output be SUTUU. Otherwise, let the output be "False". 2. Create a function called "inclusionExclusion3", where the inputs are the sets (lists) S, T, and U. The output will be SUTUU computed using the Inclusion/Exclusion Principle. Please write one-line comments (using the single line comments with #) in complete sentences that describe what each line of code does. And, don't import any packages to help you with your function
