I am trying to use dir to generate a list of methods, variables, etc.
I would like to be able to go through the list and seperate the
objects by type using the type() command, but the dir command returns
a list of strings.  When I ask for the type of an element, the answer
is always string.  How do I point at the variables themselves.  A
quick example is:

a = 5
b = 2.0
c = 'c'

lst = dir()

for el in lst:
    print type(el)

Right now I am understandably getting all types being output as
strings, how do i get the type of the actual objects returned from dir
()?

Forgive me if you are well aware of this, just thought i'd chime in with the "Duck typing speech":

Pythonic programming style that determines an object's type by inspection of its method or attribute signature rather than by explicit relationship to some type object ("If it looks like a duck and quacks like a duck, it must be a duck.") By emphasizing interfaces rather than specific types, well-designed code improves its flexibility by allowing polymorphic substitution. Duck-typing avoids tests using type() or isinstance(). Instead, it typically employs the EAFP (Easier to Ask Forgiveness than Permission) style of programming.
