Re: set function

On Sat, 17 May 2008 15:49:05 +1000, Beema shafreen
Hi all,
I need to find the intersection of 10 different files with ids definedas
a_items, b_items and so on

common_items = a_items&b_items&c_items&\

i have included above line in the script
is this an right way will my program accept it or what are the other
to compare 10 different such items
See "Set Types", http://docs.python.org/lib/types-set.html. Example:

s1 = set([1,2,3])
s2 = set([3,4,5])
s1 & s2

You can populate your sets using an iterable, such as the lines from a
file. Example:

s1 = set(file(r'blah.txt'))
