Python 运行代码时发生UnboundLocalError，这毫无意义

有人能帮忙吗？ 昨天，当我完成了这段代码并测试了我所有的可能性时，它成功了。但今天它根本不起作用，它只是产生了一个错误

我的代码：

def parseCSV(string):

    results = []
    current = ''
    quoting = False
    quoting = False


    for i in range(0, len(string)):
        currentletter = string[i]

        if currentletter == '"':
            if quoted == True:
                if quoting == True:
                    current = current + currentletter
                    quoting = False 
                else:
                    quoting = True

            else:
                quoted = True
                quoting = False

        else:

            shouldCheck  = False

            if quoted == True:

                if quoting == True:
                    quoted = False
                    quoting = False

                    shouldCheck = True

                else:
                    current = current + currentletter

            else:
                shouldCheck = True

            if shouldCheck == True:
                if currentletter == ',':
                    results.append(current)
                    current = ''

                else:
                    current = current +  currentletter

    results.append(current)
    return results


# Main
#Split CSV
Result = parseCSV('a,"b,c",d')
print(Result)

错误：

UnboundLocalError: local variable 'quoted' referenced before assignment

有人能解释什么是UnboundLocalError吗？非常感谢

错误代码：错误是我设置了两次引用，而其中一个应该被引用

def parseCSV(string):

    results = []
    current = ''
    quoting = False
    quoting = False


    for i in range(0, len(string)):
        currentletter = string[i]

        if currentletter == '"':
            if quoted == True:
                if quoting == True:
                    current = current + currentletter
                    quoting = False 
                else:
                    quoting = True

            else:
                quoted = True
                quoting = False

        else:

            shouldCheck  = False

            if quoted == True:

                if quoting == True:
                    quoted = False
                    quoting = False

                    shouldCheck = True

                else:
                    current = current + currentletter

            else:
                shouldCheck = True

            if shouldCheck == True:
                if currentletter == ',':
                    results.append(current)
                    current = ''

                else:
                    current = current +  currentletter

    results.append(current)
    return results


# Main
#Split CSV
Result = parseCSV('a,"b,c",d')
print(Result)

有人能关上这个吗？谢谢

在使用if语句之前，您是否将“quoted”设置为某个值？也许你在控制台上设置了它，但忘记将其包含在主代码中。你可以删除你自己的问题。你写的，没有其他答案，所以你可以使用你的问题下的删除按钮删除它。
