I just got python and sublime 3. When I press control + b, I get this in the console:
'python' is not recognized as an internal or external command,
operable program or batch file.
If you installed Python 2, you'll need to just go ahead and install Python 3, as it's the present and future of the language. Don't starting learning Python with 2, you'll pick up all sorts of bad habits. Learn with 3, then go back and find out the differences with 2 when you can understand them. I'm assuming you're on a 64-bit system, as everything is these days, so download Python 3 from here. If you're not, get this one. Run the installer, and pick the option (I forget exactly where it is) that says "Add Python to my PATH". Finish the installation, restart Sublime, and it should pick up
python.exe just fine.
BTW, in Python 3,
Don't forget to save the file before building.
