Python’s Dictionary datatype is a class, which means it has methods directly associated with it to make working with that data easier. The clear() method allows you to empty the dictionary of all of it’s data. The get() method works similarly to the [key], where you get the value of the key. The main difference…

Remember that a string is a collection of characters which are either taken as an input from a user, read from a text file, or enclosed within quotes within our program….
A tuple is a sequence, similar to a list. The difference is that with a Tuple, it’s data is immutable. i.e. Once the data is set, it cannot change.
