The problem about python version.

Hi! everyone, I meet two problems. One is that no matter what date and time I input, the system will indicate "this is not a valid date and time", even though I am pretty sure that there is no problem with input.

Another question about python version. I cannot install pytz under the environment python 3 or above. The terminal always indicates that "There is no module about pytz". I can import pytz under the environment 2.7, however, I need to change "input" to "raw_input" in that case. But the first problem is still exist.

I really confused. Hope someone can help me. Thanks so much! by the way, I use mac, type program in sublime and run it in terminal.

This is something almost every student runs into...

By default, in Workspaces if you run a file with the python command it will run the program with Python 3.

So if you type:

python --version

in Workspaces it will return Python 3 (or a number bigger).

However, since Python 2 is the default version on a Mac, doing that command will return Python 2 (unless you've customized your computer).

So, either follow along on Workspaces or Set up a local Python Enviroment on a Mac.

After you install Python 3, you should run programs with the python3 command, and not the python command.

I hope this helps. :)

Good luck! ~alex
