If by 'extending one level above' you mean 'outside the current scope', 
then yes if isThumbnail is mutable.  ie, something like:

isThumbnail = [False]

# create scope

def inner(size):
     isThumbnail[0] = bool(size == "thumbnail")


inner('not thumbnail')
print isThumbnail


inner('thumbnail')
print isThumbnail
