i wanted to know why i was doing certain things

[imshanedulong]

Awesome tutorial and I hope you keep going! One thing, GUI is not supposed to be pronounced as a word (at least I don't think). It's G-U-I. That just confused me for a sec.

@zerocheese hmm well i don't know if you can set it up like that, but you could now probably do:

python -c "import myproject"

and it will run the code in path/to/myproject.py assuming it's in sys.path

[zerocheese]

@murftown when i say sys.path it does point to the directory i keep my python projects, is there a way i can set up python so from the command line i can just say python myproject.py?

[murftown]

@zerocheese if you want to load a python file as a module, it needs to be in the sys.path. type "import sys" and then "sys.path" to see what directories python looks in when you say "import whatever". if you want to add a certain directory forever and for always you need to add it to the PYTHONPATH environment variable.

[zerocheese]

@murftown Thanks, i thought there was a shorter way, like if u ran python from the same directory as the script, but its just easier to browse to the file and run it form there...

[murftown]

@zerocheese you can run it from the prompt / terminal:

> /whatever/path/to/python /whatever/path/to/your-file-he­re.py

or you can right click the .py file and see if there's an option to Open with a certain Application, then choose Python.
