In Python, everything is an object (be it a list, string etc).

A method in Python is somewhat similar to function the only difference is that a method is dependent on the object while a function is independent of the object.

Can you recall we had used a function len() in the earlier modules? Well, this is a function. len() can be used on list, tuple, strings, dictionaries, etc. to get the number of elements in them. While append() is a method that is associated with list only. You cannot use append() method on any of tuple, strings or dictionaries. This append() is associated with list data type only.

Objects have various methods associated with them (depending on type of the object).
