PySIG Meeting, 25 May 2006, Generators

[Ted Roche]

Bill Sconce entertained 5 attendees with a great presentation  
explaining generators in Python. Comparisons of FOR clauses in a  
dozen languages, discussions of the the classic gotchas with  
iterators (off-by-one, picket-fence and infinite loops) were  
discussed and inadvertently demonstrated.  We then dug into what an  
iterator is, how generators work, how assignments from tuples and  
lists and sequences work within a FOR statement and that old bugaboo,  
immutability. Excellent discussion! Working with the interpreter got  
us to dive in and test exceptional cases. In addition, folks got to  
network, swap stories, arrange for hardware repair, come up with a  
theory on how to get projectors to work best (wire everything  
together, set the laptop to the desired resolution, shut down and  
restart the projector) and enjoy milk and cookies, kindly provided by  
Janet.

It doesn't get much better than that.

Next PySIG meeting: June 22. Topic tba.
