No, Python Counter is designed to work with hashable objects. Hashable objects have a hash value that remains constant throughout their lifetime integer strings and tuples. However, if you have non-hashable objects like lists or sets, you can convert them to hashable objects before using Python Counter. For example, you can convert a list to a tuple using the tuple() function and then pass it to the Counter. Remember that the conversion process might affect the uniqueness and order of the elements.
