[Tutor] select particular directories and files

[Andre' Walker-Loud]

hello,

yes, I would also try adding a wild card in the dir search

>> for dir in glob.glob(MainFolder + '01\*'):


to check if this is helps, in an interpreter (rather than script) try

dirs = glob.glob(MainFolder + '\01\*'):
print dirs


if you get "[]" then this was not the answer, but if you get a list of directories, then this should work.

Well, it should work with the correction


>>         for ncfile in glob.glob(dir+'\*.nc'):



Cheers,

Andre
