思路:
step1:输入两个字符;并将a转化为浮点型;
step2:计算金额;
step3:判断是否需要加急;
step4:计算总金额;
代码如下:
a,b = input().split()
a = float(a)
if a <= 1:
money = 20
elif a > 1:
m,n = divmod(a,1)
money = 20 + (m - 1)*1
if n > 0:
money = money + 1
else:
money = money
if b == 'y':
print(int(money + 5))
elif b == 'n':
print(int(money))
