i've hardly ever used lambdas since map() and filter() were replaced by list 
comprehension.  two other uses I can think of for it are: using it as a 
sorting key (which takes a function and lambdas are perfect for that when a 
direct function isn't available. for example, lambda x: x.myName), and I 
made an irc bot once that certain events had a list of fuctions that would 
be called after that event.  it was like being able to dynamically add and 
remove event handlers.  for example what if you asked the user a question 
and you wanted to know for the next input whether it was from that user and 
was an answer to that question.  sometimes the function to add would be very 
simple, so writing a def for it would just be ugly.
