Associativity of operators determines the order of evaluation of operators with the same precedence level. Arithmetic,boolean,relational and bitwise operators are all left to right associated.
Relational operators are used to compare values. There are two more relational operators.

We can update a dictionary by adding a new entry or item (i.e., a key-value pair), modifying an existing entry, or deleting an existing entry.
To access dictionary elements, we can use the familiar square brackets along with the key to obtain its value.
A dictionary is mutable and is another container type that can store any number of Python objects, including other container types.
