Heh heh.  No I don't.  ;)

In fact, I don't ever use lambdas in any of my own "real" code.  But I 
don't mind being a little dirty when I post to c.l.py. ;)  I guess I 
could have written this as:

     def inverse():
         return 1/x
     def largenum():
         return 1.0e99
     b = (inverse, largenum)[x==0]()

but I'm usually too lazy, and it's an ugly solution anyway, compared to 
the simple one which the OP was apparently trying to avoid:

     if x != 0:
         b = 1/x
         b = 1.0e99
