Local and global variables

Variables created inside a function are local to that function. They cannot be seen or used outside. Variables created outside functions are global and can be read anywhere.

How it reads

• sky = "neon" is a global variable accessible inside and outside paint()
• cloud = "puffy" is a local variable only accessible inside paint()

Cloud tip: Keeping variables local helps prevent errors, because different functions won't accidentally overwrite each other's data.
