如何在python请求中发布以null为值的JSON数据

Question

我有JSON数据，需要格式化并将其发送到服务器，并将null值设置为null。 Python中的字典不能将null作为值，而可以将“ null”作为值。如何将以上内容转换为Python可以识别的字典？

a = {"name":"p_retailprice","type":"DOUBLE","comment":"","precision":null,"scale":null}
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
NameError: name 'null' is not defined

Answer 1

Python中null关键字的等效项为None。

尝试

a = {"name":"p_retailprice","type":"DOUBLE","comment":"","precision":None,"scale":None}
