[Tutor] select particular directories and files

[questions anon]

It worked! thank you. This is the code I ended with:

for dir in glob.glob(MainFolder + '*/01/'):
        print dir
        for ncfile in glob.glob(dir + '*.nc'):
                print ncfile

can you choose more than one folder with glob?
i.e. I tried:
for dir in glob.glob(MainFolder + '*/01/', '*/02/', '*/03/'):
but I received:
TypeError: glob() takes exactly 1 argument (3 given)


thanks
