sys.modules contains all modules that have been imported in the
current session. Some of those imports happen in the background,
without your knowledge ? for example, because these modules are
required by the interpreter itself, or are part of IDLE. The number
you see depends on the environment (I got 530 in ipython3, 34 in
python3, 45 in python2) and is not in any way important.
