[docs] suggestion for tutorial, section 2

[Christopher Crawford]

Hello,

   As someone just learning Python from Bash/C++ background, I would  
like to suggest a small addition to 2.1.2:
     how to execute a script inside the shell (similar to bash   
'scriptname', 'source script' or '. script'):
        import fn, or reload(fn)
     related, it would be nice to have info near the beginning of the  
tutorial how to call system commands:
	import os;  os.system('..')

--thanks, Chris
