Answer 1

It seems like you assigned a null value to a key in a dictionary inside csv.py.

Is null a variable?

If you want to assign an "empty"/"null" value in python , you should use None . null is not a type in python.

Answer 2

You can try like this:

import json
mydict = json.dumps(data)

Whatever data you are converting into dict make sure it should be json.dumps() before print or process otherwise the null will be treated as variable.
