python 100题29

题目：给一个不多于5位的正整数，要求：一、求它是几位数，二、逆序打印出各位数字。

def output(x,y):
    if y == 0:
        return
    print(x[y-1])
    output(x,y-1)
s = input("请输入正整数：")
k = len(s)
if k <= 5:
    print(k)
    output(s,k)

s = int(input("请输入正整数："))
x = s // 10000 #万
y = s // 1000 % 10 #千
z = s // 100 % 10 #百
h = s // 10 % 10 # 十
g = s % 10 # 个
if x != 0 :
    print("5位", g,h,z,y,x)
elif x == 0 and y != 0:
    print("4位",g,h,z,y)
elif x == 0 and y == 0 and z != 0:
    print("3位",g,h,z)
elif x == 0 and y == 0 and z == 0 and h != 0:
    print("2位",g,h)
elif x == 0 and y == 0 and z == 0 and h ==0 and g != 0:
    print("1位",g)
