python错误计数cs50 pset6现金

Question

硬币的数量不对

代码：

从cs50导入获取浮点数

将numpy作为np导入

尽管如此：

dollar = get_float("change owed: ")
if dollar >= 0:
    break

美分=美元*100

美分=圆形（美分，2）

硬币=0 面额=np.数组（[25,10,5,1]）

尺寸=长度（面额）

for i in range(size):
 coins += cents / denominations[i]
 cents %= denominations[i]

硬币=圆形（硬币）

印刷品（“，整数（硬币））

Answer 1

哈哈

from cs50 import get_float
import numpy as np

#prompt the user for change in dollar
while True:
    dollar = get_float("change owed: ")
#break the loop if the given input is valid
    if dollar >= 0:
        break
#convert the given input(dollar) to cents
cents = dollar * 100
#rounding the cents to two decimal
cents = round(cents, 2)
#creating a variable for counting the coins
coins = 0
#creating an array for quarter, dime, nickel, penny
denominators = np.array([25, 10, 5, 1])
#substracting the cents by the array and count the coins
for i  in range(len(denominators)):
    while cents>=denominators[i]:
        cents -= denominators[i]
        coins +=1
print("", coins)
