Решение с тернарен оператор:

change = int(float(input()) * 100)
counter = 0

while change > 0:
    change -= 200 if change >= 200 \
        else 100 if change >= 100 \
        else 50 if change >= 50 \
        else 20 if change >= 20 \
        else 10 if change >= 10 \
        else 5 if change >= 5 \
        else 2 if change >= 2 else 1

    counter += 1

print(counter)

Решение с лист:

coins = [200, 100, 50, 20, 10, 5, 2, 1]
change = int(float(input()) * 100)
counter = 0

for coin in coins:
    if change >= coin:
        counter += change // coin
        change %= coin

print(counter)
