python - Project Euler/Python : find sum of multiples of 3 and 5. 程序未继续输入

Question

我是编程新手，我正在参加 Project Euler 挑战赛，让我有理由学习。

在下面找到我非常简单的 python 代码

x = 1                       
thirdDivide = 0             
fifthDivide=0     
total = 0                   

print('Enter the max value')

maxValue = input()

while (x != maxValue):
    thirdDivide = x / 3
    fifthDivide = x / 5
    if (thirdDivide).is_integer():
        total = total + x
        x = x + 1
    elif (fifthDivide).is_integer():
        total = total + x
        x = x + 1

print ("The sum of the multiples of 3 and 5 between 0 and " + maxValue + " is " + total)

当我运行它时，它会询问我的最大值，然后停止执行任何操作。

谢谢!

假设您在 Python 3 中，使用字符串代替 float ，或使用 float 代替字符串，无限循环的修复如下:

x = 1
thirdDivide = 0
fifthDivide=0
total = 0

maxValue = float(input('Enter the max value: '))

while (x != maxValue):
    thirdDivide = x / 3
    fifthDivide = x / 5
    if (thirdDivide).is_integer():
        total = total + x
    elif (fifthDivide).is_integer():
        total = total + x
    x = x + 1

print("The sum of the multiples of 3 and 5 between 0 and " + str(maxValue) + " is " + str(total))

请注意，我不会检查您的算法是否正确以及它是否计算出它应该做什么。但现在它会产生一些结果并进行编译。
