How To Solve Type Unhashable type:set Error ?

  1. How To Solve Type Unhashable type:set Error ?

    To Solve Type Unhashable type:set Error This error is raised because a set can only contain immutable types. Or sets are mutable. However there is the frozenset type :

  2. Type Unhashable type:set

    To Solve Type Unhashable type:set Error This error is raised because a set can only contain immutable types. Or sets are mutable. However there is the frozenset type :

Solution 1

The individual items that you put into a set can’t be mutable, because if they changed, the effective hash would change and thus the ability to check for inclusion would break down.

Instead, you need to put immutable objects into a set – e.g. frozensets.

If you change the return statement from your enum method to…

return [frozenset(i) for i in L]

…then it should work.

Solution 2

This error is raised because a set can only contain immutable types. Or sets are mutable. However there is the frozenset type :

In [4]: a, b = {1,2,3}, {2,3,4}

In [5]: set([a,b])
---------------------------------------------------------------------------
TypeError                                 Traceback (most recent call last)
<ipython-input-5-6ca6d80d679c> in <module>()
----> 1 set([a,b])

TypeError: unhashable type: 'set'

In [6]: a, b = frozenset({1,2,3}), frozenset({2,3,4})

In [7]: set([a,b])
Out[7]: {frozenset({1, 2, 3}), frozenset({2, 3, 4})}
