The TypeError: unhashable type: 'list'<\/code> 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()<\/code> function. 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 a non-hashable list as a dictionary key or set element.<\/p>\n

We’ll show how this is done in the remaining article. The last method is a unique way to still use lists in sets or dictionary keys that you likely won’t find anywhere else, so keep reading and learn something new! \"\ud83d\udc1d\"<\/p>\n
