list comprehensions take care of them. Guido wanted to remove them from Python 3.

   map = lambda f, a: [f(x) for x in a]
   filter = lambda f, a: [x for x in a if f(x)]

List comprehensions cover 90% of the use cases, but I'm glad map and filter were not removed. List comprehensions do not have first class status. You can pass map and filter around as arguments to other functions, but you cannot pass around "for", "in", and "if".

You're right, but even if they were removed, see above for their definition. :)

Makes sense; thank you for the explanation.
