family = requst.json['family']
age = requst.json['age']

but, how do i get the address field and save it to a variable? 但是，如何获取地址字段并将其保存到变量？

If you have the following dictionary, 'address' is a dictionary that is nested in another dictionary: 如果您具有以下字典，则“ address”是嵌套在另一个字典中的字典：

{"name":"jane", "family": "doe",
"address":{"country":"Iran", "State": "Ilam", "city": "ilam"},
"age": "25" }

Extracting the address is done in the following way: 提取地址的方法如下：

address = request.json['address']

>>> address
{'country': 'Iran', 'State': 'Ilam', 'city': 'ilam'}

Address that you extracted is now a new dictionary, and you need to extract values from it like this: 现在，您提取的地址是一个新的字典，您需要像这样从中提取值：

state = address['State']
city = address['city']
country = address['country']
