import sys
import __builtin__ # note: no plural s
old_open = __builtin__.open
def myopen(*args):
code = sys._getframe(1).f_code
print "OPEN", args, "FROM", code.co_name, "IN", code.co_filename
return old_open(*args)
__builtin__.open = myopen
this only handles file opens that goes via the "open" function, of course.
to handle all opens, including internal operations (e.g. imports), you're
probably better off using an external tool (e.g. strace, filemon, or some-
thing similar).
