You’ll implement real use cases of pass-by-reference constructs in Python and learn several best practices to avoid pitfalls with your function arguments. In this tutorial, you’ll learn: What it means to pass by reference and why you’d want to do so; How passing by reference differs from both passing by value and Python’s unique approach
In this introductory tutorial, you'll learn all about how to perform definite iteration with Python for loops. You’ll see how other programming languages implement definite iteration, learn about iterables and iterators, and tie it all together to learn about Python’s for loop.
A Python program accesses data values through references. A reference is a name that refers to the specific location in memory of a value (object). References take the form of variables, attributes, and items. In Python, a variable or other reference has no intrinsic type.
