 - Its readable
 - It scales well
 - It is easy to learn
 - batteries included.
 - Doc-strings!
 - Its easy to maintain
 - It realy is high level. 
   - No gotos.
   - Real functions with real arguments.
   - No reference gymnastics.
 - "Reads like pseudo-code".
 - Doesn't get in the way. Often the goal isn't to code, 
   its to get something done and Pythons powerful simplicity
   gives you space to remember all the other things needed 
   to finish a task, that are not programming.
