Python Datetime Timezone Issue

[sibblegp]

python app.py
Traceback (most recent call last):
File "app.py", line 5, in
import api
File "/apps/tinder-detective/api.py", line 7, in
from datetime import timezone
ImportError: cannot import name timezone

I don't think Python 2.7 has timezone but 3.X won't run Flask. What am I missing here?

When I try to run under 3.X:

Traceback (most recent call last):
File "app.py", line 7, in
app = Flask('tinder-detective')

Set
from datetime import timezone
TO
from datetime import datetime

[rafael-azevedo]

on OSX run pip3 install datetime

Concerning the NoneType loader issue. This is happening because you are running python3.40, there seems to be a bug with that version and flask. I ran into this problem.

If you change the python version to 3.43+ it should work.
Here is the github thread for reference:

Set
from datetime import timezone
TO
from datetime import datetime

This worked. Thanks!
