Testing and Modules

A common structure convention is AAA- Arrange, Act, Assert
- Arrange- organize the data needed to execute the input
- Act- this is where the code is executed
- Assert- after running the code, check to see if the output is the expected result
Writing a test first can make writing the bulk of the code simpler because you write it to PASS the test

I have no idea what this article is saying.
from the article: “Before executing code, Python interpreter reads source file and define few special variables/global variables. If the python interpreter is running that module (the source file) as the main program, it sets the special name variable to have a value “main”. If this file is being imported from another module, name will be set to the module’s name. Module’s name is available as value to name global variable. A module is a file containing Python definitions and statements. The file name is the module name with the suffix .py appended. “

Genuinely no idea what this is. The dude just said factoral 1 million times like im supposed to know what that even is.
Recursion is, in the simplest terms I can think of it, as mulitplying a number by every positive number counting down uinder it so f(6) would be 65432*1=144
