i'm learning python, learn with me.

 if i wanted to run a separate program in python, what would be the best way to code this?     =====    

 but one i might actually be able to code is a simple webcrawler if i use wget. its kind of interesting actually.

 well see, i bought an awesome book on python and have been reading it also.. i have made it to about chapter 4. but i feel i didnt really grasp what i read, so im going to start over from the beginning.
