From the lesson: Writing Clean Python: Comments, Docstrings, and PEP 8

Imagine opening a cookbook where every recipe is scribbled in messy handwriting, with no labels, no ingredient lists, and no spacing between steps. You could figure it out eventually, but it would be painful. Code works the same way.

Read the lesson

The code below is messy. Rewrite it following PEP 8 rules:

def calcArea(W,H):
  result=W*H
  return result
def calcPerimeter(W,H):
  result=2*(W+H)
  return result
w=8
h=5
print(f"Area: {calcArea(w,h)}")
print(f"Perimeter: {calcPerimeter(w,h)}")

Fix these issues:

Function names should be snake_case

Use 4 spaces for indentation

Add spaces around operators and after commas

Add two blank lines between function definitions

Use meaningful variable names

The output must be:

Area: 40
Perimeter: 26
