Detecting Binary content in files

[ritu]

Hi,

I'm wondering if Python has a utility to detect binary content in
files? Or if anyone has any ideas on how that can be accomplished? I
haven't been able to find any useful information to accomplish this
(my other option is to fire off a perl script from within m python
script that will tell me whether the file is binary), so any pointers
will be appreciated.

Thanks,
Ritu
