The section of code below, which simply gets the __file__ attribute of

Given that many modules are complicated and even have dynamic
population this figure seems very high to me. it would seem very high
if one just considered the time it would take to load the pyc files
off the disk vs... whatever happens when module.__file__ happens.
The calculation appears to be cached though, so a subsequent check
does not take very long.
From once python starts and loads the main module to after all the
imports occur and this section executes takes 1.3sec. This section
takes 0.5sec. Total module count is ~800.
Perhaps some of the modules use a delayed import mechanism.
Python version is 2.5.1
Code:
################################
for module in sys.modules:
try:
path = module.__file__
except (AttributeError, ImportError):
return
If any modules lack the attribute, you will not scan them all. Perhaps
you meant 'continue'?
