Hints

An inner function can remember variables from the enclosing function.

Use nonlocal to update them.

Solution explanation

The inner function keeps value alive after make_counter returns — a closure.

Show solution

def make_counter(step):
    value = 0

    def counter():
        nonlocal value
        value += step
        return value

    return counter


step, n = map(int, input().split())
next_value = make_counter(step)
print(*[next_value() for _ in range(n)])

Output
