Creating Functions

Narrated by Gerilyn, The Coding Copywriter

Functions are groups of commands we give the computer.

print("Hey, I've used a function before.")
print("How do I make my own?")

Functions help by:

  • Making code easier to read
  • Abstracting code to work with any value
  • Making code easy to reuse
  • Dividing a complex problem into simpler ones
  • Making code easier to maintain
