M11) Stepping through a call in VS Code

A delivery charge looks wrong, so you pause the program in the VS Code debugger. In Listing 1, Breakpoint A is on the call to delivery_fee, and Breakpoint B is on print(total). Both breakpoints are enabled. Execution is paused at Breakpoint A, before that line runs, so fee does not have a value yet.

Listing 1: Program paused before a delivery charge is calculated.

def delivery_fee(distance_km: int) -> int:
    if distance_km <= 5:
        return 2
    return 5


def order_total(subtotal: int, distance_km: int) -> int:
    fee = delivery_fee(distance_km)  # Breakpoint A
    return subtotal + fee


def main() -> None:
    total = order_total(20, 6)
    print(total)  # Breakpoint B


main()

You want to inspect distance_km inside delivery_fee, return to order_total, finish the assignment to fee, inspect it on the following line, and then run to Breakpoint B. Which sequence of VS Code debugger controls does that?
