Regexp problem when parsing a string

[Alessandro Marino]

I'm a beginner and I was trying to write a program to parse recursively all
file names in a directory specified as parameter. The problem is that I get
a "None" printed to stdout when a file is positively matched. While when the
file name doesn't match the regexp the output seems ok.

C:\>c:\python.exe g:\a.py sample
====> foo - bar.txt , first part is: foo
None
skipping: foo.txt

Instead I expect an output like this one:

C:\>c:\python.exe g:\a.py sample
====> foo - bar.txt , first part is: foo
None
skipping: foo.txt

Could anyone help me to figure out why "None" appears in the putput?

Thanks and regards,
Ale
