Invent Your Own Command 🏭

print(), len(), input() — you've been using commands somebody else built. Today you build your own.

A function is a bundle of code with a name. You create one with def:

def cheer():
    print("GO TEAM GO!")
    print("🎉🎉🎉")

Three things to notice:

• def means "define" — you're inventing a new command
• the parentheses () and the colon : are required
• everything indented underneath belongs to the function

Here's the surprising part: running that code prints nothing! def only builds the function, like writing a recipe. To actually run it you call it by name:

cheer()
cheer()

Now it runs twice. That's the magic: write it once, use it forever. 🔁

Your mission

1. Build a function called cheer with def cheer():
2. Make it print at least 2 lines
3. Call it 3 times below the function
