I have started off with Python today and stuck with a weird problem. I am using Python 3.5.1 and Sublime text 3 and have written a basic hello world program.
p
press Shift-Ctrl-B and select python. That happens because the program only checks if your python program is correctly. The next time just pressing Ctrl+B, will work
In my case I needed set Build System to Python. Only it solved for me.
Solved it,
Press Ctrl+Shift+B after which a list pops up, select python from that list and its done. From next time just pressing Ctrl+B will work.
'Ctrl+Shift+B' Means "Build this code and then RUN it" instead of simply compile it
