dev_appserver.py does nothing in CMD on windows
Finally solved my issue.... turns out goodle cloud sdk requires python 2.7. I uninstalled python 3.8, installed python 2.7. dev_appserver then didn't run unless I went into the folder where it exists: 
user/name/local/google/cloudsdk/bin
And then I run python dev_appserver.py and it works.
I also had to make sure my python command worked by adding it into my path. Python3.8 makes it easy to do via install wizard, but 2.7 requires you to go into your environment vars yourself to add it. This is why my python command originally did nothing.
Not related - but my Blender 2.81 stopped working after this. I found out blender requires Python3. So I installed Python3.8 again and got both cloud sdk and blender working. Took way too many hours to solve this.... damn...
I installed python and google cloud sdk. I'm trying to use:
dev_appserver.py app.yaml
When I go to my directory with my web app (using cd [directory]) and enter dev_appserver.py app.yaml into the command line nothing happens. The prompt shows the next line in CMD like I didn't enter anything... I indeed have an app.yaml file and this works perfectly on my MacBook running a local server.
I also tried just typing "dev_appserver.py" and hitting enter and again nothing happens... It's as if I were to press enter in the command line without typing anything.
On MacBook when I type dev_appsever.py without pointing to an app.yaml file - it at least shows me all the potential commands associated with dev_appserver.py. Why doesn't the windows command prompt seem to understand this command? Nor tell me it doesn't understand it? Please help!!! I really want to run a local server for cloud engine on my Windows machine, but have no idea what's wrong. I google'd a bunch and haven't found someone else with this issue...
