Can I use mutable types as keys in dictionaries?

Can I use mutable types as keys in dictionaries?

In Python, you cannot use mutable types like lists or dictionaries as keys in dictionaries because they are not hashable.

What happens if I try to use a list as a key?

If you try to use a list as a key, you'll get a TypeError stating that lists are unhashable.

Are there any exceptions or workarounds?

You can convert mutable types to immutable types, like using tuples instead of lists, which can be used as keys.

Can you give me an example of using a tuple as a key?

Sure! You can create a dictionary like this: my_dict = {(1, 2): 'value'} where (1, 2) is a tuple used as a key.
