I have a list of lets say 300 lenght. Each element consists tuple. Every tuple has 2 arrays. How can I count the unique tuples? I have 300 tuples here and I want to know how many of them are unique. I’m trying with converting list to the set and checking its len but I have such error:
---------------------------------------------------------------------------
TypeError Traceback (most recent call last)
<ipython-input-46-24c20fbb5e62> in <module>
----> 1 len(set(pair_list))
TypeError: unhashable type: 'list'
My list looks like this:
[
(array([ 0., 0.1, 0., -0.2, -0., -0.2, 0., 0.1], [ 0.5, 0.2, 0.3, -0.1, -0.4, -0.2, 0.2, 0.1]), array([ 0.123, 0.14, 0.1, -0.22, -0.5, -0.2, 0., 0.1])),
...,
(array(...), array(...))
]
Edit: This is real sample of my data. Just one element of the list:
[array([[-0.63434589, -0.29900576, 1.58925953, 1.58925953, -1.25893308,
0.76126064, -0.87056499, 0.31736156, -3.86900902, -1. ,
-0.23059131, -0.78751513, 0.510954 , -1. , -0.30160512,
1. , 5.8423382 , 0.02629687, 0.02696755, 1.65819659,
4.21574931, -1. , 0. , 1. , 0. ,
0. , 0. , 0. , 0. , 0. ],

array([ 0. , 0.14983, 0. , -0.26847, -0. , -0.26847,
-0. , 0.14983])],
>Solution :
You need to convert the lists to tuples, to be able to create a set out of them:
pairs_1 = [
[1,2], [3,4], [5,6], [7,8]
]
print(len(set(tuple(p) for p in pairs_1)))
Out:
