TypeError: keys must be str, int, float, bool or None, not tuple 这个错误通常发生在使用 json 模块序列化包含元组(tuple)作为键的字典时。JSON 格式要求字典的键必须是字符串(str)、整数(int)、浮点数(float)、布尔值(bool)或空值(None),而不支持元组作为键。 1. 识别错误信息的含义 错误信息 TypeError...
json.dump(a, json_obj) # TypeError: keys must be str, int, float, bool or None, not tuple 1. 2. 3. 错误的信息为:虽然python允许你的字典键值为元组,但是我json不认同,你的字典键值不可以是元组,此时应该怎么办呢? 我想到了两个方法: 第一个方法是把数据转换为层次型数据,建立两层索引; 第二...

Doing it at the key-level should be safe enough. You will at most cause problems for your own application or test program. Just make sure to not propagate the permissions when you set them on the key you are interested in.Friday, March 6, 2015 3:56 PMI believe user has 'Full ...
