Question

我正在制作一个循环输出的代码，然后要求用户再次运行它，如果他们愿意

我的代码是：

    import random

    duplicateNumber=0

    def has_duplicates(listToCheck):
        number_set = set(listToCheck)

        if len(number_set) is not len(listToCheck):
            return True
        else:
            return False 

    for i in range(0,1000):
        birthdayList=[]

        for j in range(0,23):  
            birthday=random.randint(1,365)
            birthdayList.append(birthday)

        x = has_duplicates(birthdayList)

        if x==True:
            duplicateNumber+=1

    print ("after 1000 simulations with 23 students there were", duplicateNumber,"simulations with at least one match")


 code with while loop:
import random

duplicateNumber=0

def has_duplicates(listToCheck):
    number_set = set(listToCheck)

    if len(number_set) is not len(listToCheck):
        return True
    else:
        return False 
i=0
while True:
    if i>0:
        prompt = input('Do you wish to continue?')
        if prompt.lower() == 'no':
            break
    birthdayList=[]

    for j in range(0,23):  
        birthday=random.randint(1,365)
        birthdayList.append(birthday)

    x = has_duplicates(birthdayList)

    if x==True:
        duplicateNumber+=1
    i += 1

print ("after ", i," simulations with 23 students there were", duplicateNumber,"simulations with at least one match")

我尝试添加一个while循环，但它会继续询问问题而不显示输出。我希望我的代码显示输出，提示用户是否要再次运行它。如果他们说是，它会再次显示输出，然后询问他们是否想再次运行它。这一直持续到用户说不，程序结束，我该怎么做？

import random

duplicateNumber=0

def has_duplicates(listToCheck):
    number_set = set(listToCheck)

    if len(number_set) is not len(listToCheck):
        return True
    else:
        return False 
i=0
while True:
    if i>0:
        prompt = input('Do you wish to continue?')
        if prompt.lower() == 'no':
            break
    birthdayList=[]

    for j in range(0,23):  
        birthday=random.randint(1,365)
        birthdayList.append(birthday)

    x = has_duplicates(birthdayList)

    if x==True:
        duplicateNumber+=1
    i += 1

    print ("after ", i," simulations with 23 students there were", duplicateNumber,"simulations with at least one match")

只需将print()移到while循环中即可解决问题。

循环代码直到用户输入终止代码
