Help on built-in function __import__ in module __builtin__:
__import__(...)
__import__(name, globals={}, locals={}, fromlist=[], level=-1) -> 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
fromlist is not empty. Level is used to determine whether to perform
absolute or relative imports. -1 is the original strategy of attempting
both absolute and relative imports, 0 is absolute, a positive number
is the number of parent directories to search relative to the current module.
