的每个键和值转换为字符串。
我尝试了以下代码：
dict我们必须像下面表示的那样在def convert_dict_to_str_dict(data_dict):
converted_dict = {}
for key, value in data_dict.items():
if isinstance(value, dict):
converted_dict[str(key)] = convert_dict_to_str_dict(value)
else:
converted_dict[str(key)] = str(value)
return converted_dict
data_dict = {
1: 123,
'string' : 'this is a string',
'data' : {
123: 2345,
'we' : {
1: 100,
2: 'two hundred'
},
345 : 15427
}
}
上方进行转换。
