How to overcome “datetime.datetime not JSON serializable”?

Question

I have a basic dict as follows:

sample = {}
sample[\'title\'] = \"String\"
sample[\'somedate\'] = somedatetimehere
         


        

Answer 1

Actually it is quite simple. If you need to often serialize dates, then work with them as strings. You can easily convert them back as datetime objects if needed.

If you need to work mostly as datetime objects, then convert them as strings before serializing.

import json, datetime

date = str(datetime.datetime.now())
print(json.dumps(date))
"2018-12-01 15:44:34.409085"
print(type(date))


datetime_obj = datetime.datetime.strptime(date, '%Y-%m-%d %H:%M:%S.%f')
print(datetime_obj)
2018-12-01 15:44:34.409085
print(type(datetime_obj))

As you can see, the output is the same in both cases. Only the type is different.
