Hi all!

So I have a small Python program I'm trying to get working on my Mac downloaded from here: https://gitlab.com/bharadwaj-raju/WeatherDesk . It's a nifty script that changes the desktop wallpaper depending on the local time and weather conditions. I'd like to configure it and have it run automatically each time I start my machine.

Unfortunately I can't get it to run without throwing up an error. I've downloaded the new version of Python (3.6.5) and I'm trying to run the script (moved to a folder in my Applications directory) with the following code in Terminal:

cd '' && '/usr/bin/pythonw' '/Applications/WeatherDesk/WeatherDesk.py' && echo Exit status: $? && exit 1

The output is:

[inline]Traceback (most recent call last):
File "/Applications/WeatherDesk/WeatherDesk.py", line 30, in <module>
import urllib.error
ImportError: No module named error[/inline]

Could this be a problem with something in the script, or my Python configuration, or some quirk specific to a Mac? I know nothing about Python unfortunately, but I'd be appreciative of anyone who could hold my hand through getting this script working as I spent the previous night downloading and editing wallpapers for it!

You get error because you run Python 2 /usr/bin/pythonw

Doing it Right Mac
Then you test,if follow that link python will point to python 3.

# Do I have a Python 3 installed?
$ python --version # or python3 --version
Python 3.6.5 # Success!
# If you still see 2.7 ensure in PATH /usr/local/bin/ takes pecedence over /usr/bin/

If python3 point to your python 3.6.5.

$ python3 WeatherDesk.py --help

Thanks snippsat! This definitely put me in the right direction. The problem does indeed stem from Mac OS's preference for the version of Python 2 that comes preinstalled. I thought installing the latest version from the official Python site would've been enough for it to take precedence, but no.

The linked instructions proved to be a bit more than what I needed. But for anyone else who stumbles upon this thread, I found I was able to launch my script with Python 3 by changing the cd command in my launch code from /usr/bin/pythonw to /Library/Frameworks/Python.framework/Versions/3.6/bin/python3.6. A little clunky, but it proved easier to just change the Python version used for launching this script then to change things globally. Using Python 3 allowed my script to find the urllib module it could't find in Python 2.

Thanks again!
