当抛硬币的整个过程完成后，无法计算出如何使python抛硬币程序循环回到某个点

Question

我的头撞在墙上已经有几个小时了，我想弄清楚这个问题，所以我非常感谢你的帮助。我要做的是在一个Y/N问题的Y输入上循环程序，特别是当Y被输入时，我希望它以示例输出中所示的方式进行反应。在

这是我的代码：

import random
def main():
    name = eval(input("Hello user, please enter your name: "))
    print("Hello", name ,"This program runs a coin toss simulation")
    yn = input("Would you like to run the coin toss simulation?(Y/N):")
    if yn == Y:

    elif yn == N:
        print("Ok have a nice day!")

    heads = 0
    tails = 0
    count = tails + heads
    count = int(input("Enter the amount of times you would like the coin to     flip: "))
    if count <= 0: 
        print("Silly rabbit, that won't work")
    while tails + heads < count:
        coin = random.randint(1, 2)
        if coin ==1:

            heads = heads + 1
        elif coin == 2:

            tails = tails + 1
    print("you flipped", count , "time(s)")
    print("you flipped heads", heads , "time(s)")
    print("you flipped tails", tails , "time(s)")
main()

下面是我要查找的示例输出：

^{pr2}$

我想你应该说在第6行if yn == 'Y'，而不是if yn == Y。将Y视为变量，而它实际上是输入中的字符串。在
