d = {} OR d = dict()
We are creating empty dictionary. We can add entries as follows
1) d[100]="durga"
2) d[200]="ravi"
3) d[300]="shiva"
4) print(d) {100: 'durga', 200: 'ravi', 300: 'shiva'}
If we know data in advance then we can create dictionary as follows
d = {100:'durga' ,200:'ravi', 300:'shiva'}
d = {key:value, key:value}
