Multiple Parameters & Return Values in Python | Data Science
Welcome back! In this video we go one step further with Python functions.
You'll learn how to:
Pass multiple arguments to a function
Work with tuples — Python's immutable, ordered container
Unpack a tuple into separate variables in a single line
Return multiple values from a single function call
All examples are built around a real e-commerce orders database — quantities, unit prices, totals and discounts — the kind of data you work with constantly in Data Science projects.
