Python Sets - Copying Sets and Testing for Membership

(Page 3 of 6 )

If you want to copy a Set, you can do so pretty simply:

/usr/local/bin/python

mcdonaldgang = Set (['Grimace', 'Hamburglar', 'Mayor Mccheese', 'Burger King', 'Wendy', 'Fry Guy'])

gang = mcdonaldgang.copy()

print gang

Here would be the result of this program:

  Fry Guy Grimace Mayor Mccheese Hamburglar Burger King Wendy

Suppose the gang had grown so large Ronald couldn't keep track of it in his head. To see if someone was in his gang, he could use the In operator.

/usr/local/bin/python

mcdonaldgang = Set (['Grimace', 'Hamburglar', 'Mayor Mccheese', 'Burger King', 'Wendy', 'Fry Guy'])

'Grimace' in mcdonaldgang

'Birdie' in mcdonaldgang

This program checks to see if Grimace and Birdie are in the McDonald's Gang. Here is the result:

  True

  False

Meaning that Grimace is in the gang, but Birdie is not. Who cares...she was annoying anyway. And now you know where those chicken nuggets come from.
