[Tutor] selecting specific items from a list

[Praveen Pathiyil]

I feel that the following should do the job for you...

list1 = [(3,3),(2,0),(5,5), (1,1), (4,5), ('a','a'), ('a','e'), ('b','b'),
('c','d')]
eq_list = []

for (x,y) in list1:
    if x==y:
        eq_list.append(x,y)

Regards,
Praveen.
