Does the def line run the function?

Short answer. No. It is only saved.

What does a call do?

It jumps into the function and back at the end.

Remember

def is saved, not run
A call jumps in
At the end, it jumps back

The def is on top. Does it run first? No. Python only saves the def. It prints A first. Then the call tea jumps in and prints B. Then it jumps back. A def is saved, not run. A call jumps in. At the end, it jumps back.
