-Operations on Dictionary in Python-

 Think of a few scenarios in which we can use a dictionary? 

. So, today we will see how we can use the dictionary to maintain a database of Countries and their capitals.

 When we create a database, what are the operations we expect to do on it? 

 ● Insert

 ● Delete

 ● Display

 ● search

 Let us see the functions/methods, which help us in doing these.
