Encode function to JSON

Question

I have an array with an element from the operator module. I tried storing this with JSON but but got the following error msg.

import operator as op
import json
array = [1,op.ge]
json_encoded = json.dumps(array)
f = open("test.json","w")
f.write(json_encoded)
f.close()

TypeError: <built-in function ge> is not JSON serializable

is there a workaround or another way to store this?

Answer 1

You could use the pickle module, which can serialize objects, too:

import pickle
...
pickle_encoded = pickle.dumps(array)
...

Pickle will write a byte-stream, which won't be human-readable in contrast to JSON.
