Hello, I am trying to make an app that can get information off the internet and display it within the frame. Any idea where I would start with this in Python?

For example some things I would like to be able to do are:
-Make an app that diplayed weather information from weatherbug
-display time from time.gov rather than system clock
-Stock quotes mabye?

I am fairly good at manipulating data once I can get it but I have never attampted to get it from the internet before. Any help in this area or just a point in the right direction would be greatly appreciated!

Thanks!
