Python is actually quite strongly typed, it just doesn't require
declarations of the types of variables to be used, and they can be
changed.

    a = 1               # a refers to an int
    a = '1'             # a now refers to a string
    a = open('/a/file') # a now refers to a file object

That's sort of the flip side of weakly-typed languages; if they're
weakly typed then you have to play games when you _do_ need to know the
type of an object.
