Remember: A function is a named bundle of lines. Def writes it down, a call runs it, and a parameter is a blank you fill in.
Read and answer
Read the story, then answer.
The finaleBo's finale is a spin, a clap and a bow, and it happens three times in the show. Mina typed the three moves three times and had nine lines. Then she wanted a deeper bow, so she had to fix it three times. Ms. Ola says a function is a bundle of lines with a name. Mina writes def cheer(): and pushes the moves in under it. When she runs it, Bo stands still, because def only writes the recipe down. To make Bo cheer, Mina calls the function by writing cheer() on a line of its own. Later she makes a function with a blank, a parameter: greet("Bo") says hi Bo, and greet("Teo") says hi Teo.
