将字符串输出解析为python数据结构

您需要一个函数将输出字符串解析为所需的格式。我做的这是一个简单的解析器，可以创建所需的输出。让我知道是否有效。

partition_ = "[{'3', '4'}, {'1', '2', '5', '6', '7', '8', '9'}]"


def custom_parser(string):

    list_of_sets = []

    temp = []

    begin_set = False

    for char in string:

        if begin_set:

            if char == '}':

                begin_set = False

                temp2 = set(temp)

                list_of_sets.append(temp2)

                temp = []

            elif char not in ['\'', ',', ' ']:

                temp.append(char)

        if char == '{':

            begin_set = True

    return list_of_sets


new_partition_ = custom_parser(partition_)
