递归对比json

遇到个问题：

如果list中是dic，sort会报错，解决办法：sorted(a,key=lambda x:x["x"])

def compare_data(src_data, dst_data):
    if isinstance(src_data, dict):
        """若为dict格式"""
        for key in dst_data:
            if key not in src_data:
                print("src不存在这个key")
        for key in src_data:
            if key in dst_data:
                # thiskey = key
                """递归"""
                compare_data(src_data[key], dst_data[key])
            else:
                print("dst不存在这个key")
    elif isinstance(src_data, list):
        """若为list格式"""
        if len(src_data) != len(dst_data):
            print("list len: '{}' != '{}'".format(len(src_data), len(dst_data)))
            compare_flag = 0
        sort_key = ''
        for key in src_data[0]:
            sort_key = key
        for src_list, dst_list in zip(sorted(src_data,key=lambda x:x["%s" % sort_key]), sorted(dst_data,key=lambda x:x["%s" % sort_key])):
            """递归"""
            compare_data(src_list, dst_list)
    else:
        if str(src_data) != str(dst_data):
            print("%s != %s, 比对失败" % (src_data, dst_data))
