如何让我的程序复位，并添加一个继续提示，将自动重新启动程序

Question

我创造了一个一次最大的计算器为举重。一切运行正常，但我希望它以一个重启提示结束，以防用户想要计算另一个电梯。（请记住，我对编码和Python非常陌生）。你知道吗

我已经使用了不同的变量，但是我正在努力正确地声明函数，然后运行循环。你知道吗

Welcome= 'Hello and welcome to one rep max calculator, Please follow the prompt below'
print (Welcome)

reps= int(input('Rep Count?'))

initial_weight= int(input('Weight lifted?'))

bench_max=(.0333 * reps + 1) * initial_weight
print (bench_max)

reply= 'y'

question= 'Do you want another calculation?'
def yes_or_no(reply):
    reply= 'y'

    while "the answer is invalid":
        reply = str(input(question+' (y/n): ')).lower().strip()
        if reply[0] == 'y':
            return True
        if reply[0] == 'n':
            return False

yes_or_no(reply)

没有错误消息，但是程序不会重新启动，不管我是否点击yes

一旦你解决了约翰尼·莫普指出的问题，你就可以

def yes_or_no(reply):
    reply= 'y'

    while "the answer is invalid":
        reply = str(input(question+' (y/n): ')).lower().strip()
        if reply[0] == 'y':
            return True
        if reply[0] == 'n':
            return False

while True:
    Welcome= 'Hello and welcome to one rep max calculator, Please follow the prompt below'
    print (Welcome)

    reps= int(input('Rep Count?'))

    initial_weight= int(input('Weight lifted?'))

    bench_max=(.0333 * reps + 1) * initial_weight
    print (bench_max)

    reply= 'y'

    question= 'Do you want another calculation?'

    if (not yes_or_no(reply)):
        break
