List未被Bubb排序

Question

有一个气泡排序程序，我想电子邮件被按字母顺序排序。但是，当我用我想要排序的列表运行程序时，我得到一个错误TypeError:“tuple”对象不支持项分配。 代码如下：

def BubbleSort(logindata):
    NoSwaps = 1
    N = len(logindata)
    while NoSwaps == 1:
        Count = 1
        NoSwaps = 0
        for Count in range(N-1):
            if logindata[Count] > logindata[Count+1]:
                temp = logindata[Count]
                logindata[Count] = logindata[Count+1]
                logindata[Count+1]=temp
                NoSwaps=1
    return logindata

if __name__ == "__main__":
    logindata=["tom@gmail.com","Password1"],["Harry","Password2"],["Jake","Password3"]
    BubbleSort(logindata)
    print(logindata)

该程序排序不带“密码”的列表。如何让代码运行并成功排序。你知道吗

Answer 1

此代码将运行并对列表排序。但是我不知道你是不是想这样做。你知道吗

def BubbleSort(logindata):
    NoSwaps = 1
    N = len(logindata)

    while NoSwaps == 1:
        Count = 1
        NoSwaps = 0

        for Count in range(N-1):
            if logindata[Count][0] > logindata[Count+1][0]:
                temp = logindata[Count][0]
                logindata[Count][0] = logindata[Count+1][0]
                logindata[Count+1][0] =temp
                NoSwaps=1
                temp = logindata[Count][1]
                logindata[Count][1] = logindata[Count+1][1]
                logindata[Count+1][1] =temp
    return logindata

if __name__ == "__main__":
    logindata=["Adam","Password1"],["Harry","Password2"],["Cake","Password3"]
    BubbleSort(logindata)
    print(logindata)

假设冒泡排序算法工作正常，您的问题是无法在tuple中分配项，当尝试logindata[count] = logindata[count+1]时，您可以将logindata更改为list，然后返回logindata的tuple，还应该捕获返回的logindata，然后打印它，整个代码如下所示：

def BubbleSort(logindata):
    NoSwaps = 1
    N = len(logindata)
    logindata = list(logindata)
    while NoSwaps == 1:
        Count = 1
        NoSwaps = 0
        for Count in range(N-1):
            if logindata[Count] > logindata[Count+1]:
                temp = logindata[Count]
                logindata[Count] = logindata[Count+1]
                logindata[Count+1]=temp
                NoSwaps=1
    return tuple(logindata)

if __name__ == "__main__":
    logindata=["tom@gmail.com","Password1"],["Harry","Password2"],["Jake","Password3"]
    logindata = BubbleSort(logindata)
    print(logindata)
    #(['Harry', 'Password2'], ['Jake', 'Password3'], ['tom@gmail.com', 'Password1'])
