Question

我很难跟踪输入的总数。我希望我的程序跟踪输入的总数并在while循环中断时将其打印出来。任何帮助表示赞赏！

r = float(input("enter r:"))

def main(r):
    a = 3.14 * (float(r ** 2))
    s_v = 0
    total = 0

    while True:
        r = float(input("enter r:"))

        if r == sentinal_value:
            total += r
            print("Total = " , total)
            break

        else:
            print("Area = ", a)

            continue

main(r)

我假设您希望您的程序在每次迭代时都重新计算面积。按照书面规定，它将仅在您第一次运行mymian函数时计算。您无需将任何参数传递给函数。

def mymian():

    sentinal_value = 0
    total = 0

    while True:
        r = float(input("enter r:"))

        if r == sentinal_value:

            print("Total number of r provided to this program" , total)
            break

        else:
            print("Area = ", 3.14 * (float(r ** 2)))
            total += 1
            continue
