Question

I am currently working with a script that has lists that looks like this:

example = [ ((2,1),(0,1)), ((0,1),(2,1)), ((2,1),(0,1)) ]

Now turning this list to a set returns:

set( [ ((2,1),(0,1)), ((0,1),(2,1)) ] )

For my purposes I need to recognize these tuples as being equal as well. I dont care about retaining the order. All solutions I can think of is really messy so if anyone has any idea I would be gratefull.

Answer 1

In [10]: set(tuple(sorted(elt)) for elt in example)
Out[10]: set([ ((0, 1), (2, 1)) ])
