Berker Peksag <[email protected]> added the comment:
This is already documented in the json.dump() documentation:
The json module always produces str objects, not bytes objects.
Therefore, fp.write() must support str input.
Note that the traceback you've posted doesn't have anything to do with the json
module and it's expected:
>>> f = open('/tmp/t.json', 'wb')
>>> f.write('foo')
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
TypeError: a bytes-like object is required, not 'str'
