Sorry, I fell face down on the Send button :-)

To check all .py files in the current directory, modify Peter's code
like this:

import glob
for filename in glob.glob('*.py'):
   content = open(filename).read()

maybe that UnicodeDecodeError should be ...Encode...
and change the print statement to cater for filename being variable.

If you have hundreds of .py files in the same directory, you'd better
modify the code further to explicitly close each file.

HTH,
