按照题目要求编写的Python找零钱程序如下
def smallchange(money):fifty=50
ten=10
five=5
one=1
print(money//fifty,end=' ')
money=money%fifty
print(money//ten,end=' ')
money=money%ten
print(money//five,end=' ')
money=money%five
print(money//one)
l=[]
n=int(input())
for i in range(n):
l.append(input())
for i in range(n):
pay,payable=l[i].split(' ')
money=int(pay)-int(payable)
smallchange(money)
