Unhashable type list

The TypeError: unhashable type: 'list' usually occurs when you try to use a list object as a set element or dictionary key and Python internally passes the unhashable list into the hash function, unhashable type list. But as lists are mutable objects, they do not have a fixed hash value. The easiest way to fix this error is to use a hashable tuple instead of unhashable type list non-hashable list as a dictionary key or set element.

It will allow Python to create unique hash values for the keys. This error shows that the fruits key [2,4,6 ] is a list and not a hashable type in Python. Dictionary keys must be immutable types, and the list is a mutable type. The easiest way to resolve this error is to convert the list into a tuple. Though tuples may seem similar to lists, they are often used for different purposes. Tuples are immutable and contain a heterogeneous sequence of elements that are accessed via unpacking or indexing. On the other hand, lists are mutable, and the elements are homogeneous, and the elements are accessed by iterating over the list.

In this guide, we talk about what this error means and why you see it in your code. Dictionaries have two parts: keys and values. Keys are the labels associated with a particular value.

In python, there are many types of errors as once the code has many types of problems in which this error will come. Errors will always define which type of problem has occurred in the solution. Now there is a problem to know which object is hashable and which object is not. Now we are trying to find hash value for the set and when are printing the value the error occurs as the hash value is not coming so we cannot use it as a key in the dictionary in the set. So to avoid this error by removing the mutable object or replacing it with some immutable object and your code will run properly.

This article will discuss the TypeError: unhashable type: 'list' and how to fix it in Python. Dictionaries is a data structure in Python that works in key-value pairs, every key has a value against it, and to access the values of values, you will need the keys like array indices. We have used a list ["a","b"] as the key , but the compiler has thrown a TypeError: unhashable type: 'list'. The hash function is used to find the hash value of a given object, but the object must be immutable like string , tuple , etc. To fix the TypeError in Python, you have to use immutable objects as the keys of dictionaries and as arguments to the hash function. Notice in the above code the hash function works perfectly with mutable objects like tuple and string. This time we provide a string "a" as the key, which is fine to work with because strings are mutable.
