Python works differently from languages that support passing arguments by reference or by value. Function arguments become local variables assigned to each value that was passed to the function. But this doesn’t prevent you from achieving the same results you’d expect when passing arguments by reference in other languages.
In this course, you learned:
- How Python handles assigning values to variables
- How function arguments are passed by assignment in Python
- Why returning values is a best practice for replicating pass by reference
- How to use attributes, dictionaries, and lists as alternative best practices
