Get count of tuples in list regardless of elements orders

Question

I have a list of tuples that looks something like this:

my_list = [(1,12),(12,1),(12,1),(20,15),(7,8),(15,20)]

I want to get a count of the num

Answer 1

First you can sort your list

lst2 = [tuple(sorted(i)) for i in lst]

Then you can use set() to find the unique values in this list and count their occurence.

count = {}
for i in set(lst2):
    num = len([1 for j in lst2 if j == i])
    count.update({i:num})
print(count)

{(1, 12): 3, (7, 8): 1, (15, 20): 2}
