Eg1:-

         x={}
         print(x)
         print(type(x))
Output:
             {}
             <class 'dict'>
Eg2:-
         y=dict
         print(y)
         print(type(y))
Output:
            <class 'dict'>
            <class 'type'>
Eg3:-
         z={"jaja":80,"python":99,"handdop":86}
         print(z)
Output:
             {'jaja': 80, 'python': 99, 'handdop': 86}
Eg4:-
         x={"jaja":80,"python":99,"handdop":86}
         print(x)
         print(x["python"])
         print(x.get("handdop"))
         x["aws"]=89
         print(x)
         x["devops"]=86
         print(x)
         y={101:True,123.123:"python","lokesh":3+4j}
         print(y)
Output:
              {'jaja': 80, 'python': 99, 'handdop': 86}
               99
               86
              {'jaja': 80, 'python': 99, 'handdop': 86, 'aws': 89}
              {'jaja': 80, 'python': 99, 'handdop': 86, 'aws': 89, 'devops': 86}
              {101: True, 123.123: 'python', 'lokesh': (3+4j)}
