[Tutor] Kent's top poster script operator.itemgetter()

[Sander Sweers]

Hello All,

While trying to inderstand Kent's script [1] I struggle on the use of
operator.itemgetter(1) from the following piece of code. I understand
it makes it sort on the second value of the counts.iteritems but I do
not understand how  operator.itemgetter(1) works.

for name, count in
sorted(counts.iteritems(),key=operator.itemgetter(1), reverse=True):

Could someone help me understand this?

Thanks
Sander
