You want the __import__ function:

module = __import__(var)

__import__(name, globals, locals, fromlist) -> module

Import a module.  The globals are only used to determine the context;
they are not modified.  The locals are currently unused.  The fromlist
should be a list of names to emulate ``from name import ...'', or an
empty list to emulate ``import name''.
When importing a module from a package, note that __import__('A.B', ...)
returns package A when fromlist is empty, but its submodule B when
