getattr(x, 'y') <==> x.y
vars() gives a dict representing the current accessible variable
bindings (I should have instead recommended the related globals()
function)
globals() gives a dict representing the global variable bindings
For example:
#foo.py
class Foo(object):
#code here
Foo()
#same as
globals()['Foo']()
#end of file
Cheers,
Chris
