💡 Problem Formulation: In Python, lists are mutable and therefore not hashable, which means they cannot be used as dictionary keys or stored in sets. However, there are situations where you need to convert a list into a hashable entity to perform such operations. For instance, if we have an input my_list = [1, 2, … Read more

💡 Problem Formulation: Converting a list to a hash means generating a unique value (hash) for the contents of a list such that any change in the list’s contents will produce a different hash value. This is useful for data integrity checks, dictionary keys, or caching purposes. For instance, given the input [‘apple’, ‘banana’, ‘cherry’], … Read more
