Fix: TypeError: unhashable type: slice

data_list = [slice(1, 2), slice(3, 4)]
data_set = set(data_list)

---------------------------------------------------------------------------
TypeError                                 Traceback (most recent call last)
Cell In[92], line 2
      1 data_list = [slice(1, 5), slice(5, 10)]
----> 2 data_set = set(data_list)

TypeError: unhashable type: 'slice'

Reason for the Error:

Here we are trying to convert a list of slices to a set, this is not possible because slices are mutable whereas sets are a hash-based data structure that needs their elements to be immutable.
