[Tutor] select particular directories and files

[questions anon]

Thanks for responding
When I try glob.glob I receive no errors but nothing prints.

MainFolder=r"E:/Sample/"
for dir in glob.glob(MainFolder + '01'):
        print "my selected directories are:", dir
        for ncfile in glob.glob('.nc'):
            print "my selected netcdf files are:", ncfile

any suggestions? thanks
