zip参数1在通过zip循环时必须支持迭代错误

Question

我几乎没有看到其他类似的问题报告，但我无法复制我的情况下的解决方案。

我的问题更简单，因为我有一个数字列表和一个字符串列表

number = [21, 44, 31, 553, 63, 35]
access = ["denied", "Try Again", "Retry", "Accepted", "Error", "Success"]

我压缩了它们并创建了一对，每个值如下

testInput = zip(number, access)

output: 
[(21, 'denied'), (44, 'Try Again'), (31, 'Retry'), (553, 'Accepted'), (63, 'Error'), (35, 'Success')]

我试图遍历每一对并执行我的函数，该函数根据对的值将它们映射到一个团队名称。我的尝试是：

def mapping(number, access):
    team = ''
    checkNumberAndAccess = zip(number, access)
    for number, access in checkNumberAndAccess:
        if number in range(20,30):
            team = 'Revolt'
        elif (number in range(40,50)) and (access == 'Try Again'):
            team = 'Strike'
        elif (number in range(60,100)) and (access == 'Error'):
            team = 'Exception'
    print team
    return team

我希望“Team”变量保存每对的映射输出值，因此这是我执行函数的地方：

for number, access in testInput:
    Team = mapping(number, access)
    df = df.append({'Access Message': access, 'Number': number}, ignore_index=True)
print df

在执行映射函数时，出现“TypeError:zip argument#1 must support iteration”错误。是不是放错地方了？

完整代码：

import pandas as pd

df = pd.DataFrame()


number = [21, 44, 31, 553, 63, 35]
access = ["denied", "Try Again", "Retry", "Accepted", "Error", "Success"]


def mapping(number, access):
    team = ''
    checkNumberAndAccess = zip(number, access)
    for number, access in checkNumberAndAccess:
        if number in range(20,30):
            team = 'Revolt'
        elif (number in range(40,50)) and (access == 'Try Again'):
            team = 'Strike'
        elif (number in range(60,100)) and (access == 'Error'):
            team = 'Exception'
    print team
    return team


testInput = zip(number, access)
print testInput

for number, access in testInput:
    Team = mapping(number, access)
    df = df.append({'Access Message': access, 'Number': number}, ignore_index=True)
print df

Answer 1

试试这个。

import pandas as pd

df = pd.DataFrame()


number = [21, 44, 31, 553, 63, 35]
access = ["denied", "Try Again", "Retry", "Accepted", "Error", "Success"]


def mapping(number, access):
    team = ''

    if number in range(20,30):
        team = 'Revolt'
    elif (number in range(40,50)) and (access == 'Try Again'):
        team = 'Strike'
    elif (number in range(60,100)) and (access == 'Error'):
        team = 'Exception'
    print team
    return team


testInput = zip(number, access)
print testInput

for number, access in testInput:
    Team = mapping(number, access)
    df = df.append({'Access Message': access, 'Number': number}, ignore_index=True)
print df

或者您可以从这里传递总列表并压缩到那里，处理并将最终结果返回给调用函数
