Question

我正在使用python3，我有此代码向用户询问三个输入。然后我对它们进行计算。我想继续将计算结果添加到列表中。该怎么做？

...

if choice == '1': #my fist input x
    while True:
        x = int(input('Please insert the number of things you consider yourself a fan of'))
        if x > 0:
            break
        else:
             print('Please insert a number higher than 0')

elif choice == '2': #my second input y
    while True:
        y = int(input('Please insert the number of hobbies you like to do every month'))
        if y % 4 == 0:
            break
        else:
            print('Please insert a valid number')

elif choice == '3': #my third input z
    while True:
        z = int(input('Please insert the number of sports you like'))
        if z > 0:
            break
        else:
            print('Please insert a number higher than 0')

elif choice == '4': #the calculation part
    import math
    def square_root():
        c=(42 * y ** 2)/(z + 1)
        nerd_score=int(x*math.sqrt(c))
        return nerd_score
    print('your nerd score is', square_root())

我希望循环继续进行，并将每个结果添加到列表中。直到用户退出循环。

据我了解，您要解决两个问题：

循环继续进行，util用户希望退出循环
将每个结果添加到列表中

示例代码在这里：

def loop_calculation(choice):
    # record results in list
    results = []

    # loop keep going, util user input choice 'x' which means exit
    while choice != 'x':
        if choice == '1':  # my fist input x
            while True:
                x = int(input('Please insert the number of things you consider yourself a fan of'))
                if x > 0:
                    break
                else:
                    print('Please insert a number higher than 0')

        elif choice == '2':  # my second input y
            while True:
                y = int(input('Please insert the number of hobbies you like to do every month'))
                if y % 4 == 0:
                    break
                else:
                    print('Please insert a valid number')

        elif choice == '3':  # my third input z
            while True:
                z = int(input('Please insert the number of sports you like'))
                if z > 0:
                    break
                else:
                    print('Please insert a number higher than 0')

        elif choice == '4':  # the calculation part
            import math

            def square_root():
                c = (42 * y ** 2) / (z + 1)
                nerd_score = int(x * math.sqrt(c))
                return nerd_score

            result = square_root()
            print('your nerd score is', result)

            # add each result to list
            results.append(result)

    return results

希望它会对您有所帮助。

将while循环用户添加到列表中输入计算。 Python3
