Appending Values to a Dictionary

☞ To add a new item to the existing dictionary, extend it with a single pair of values.

Syntax :

 
<dictionary_name> [<key>] = value

Example :

 
D = {10:"Ten", 20:"Twenty"}
print(D)
D[30] = "Thirty"
print(D)

Output :

 
{10: 'Ten', 20: 'Twenty'}
{10: 'Ten', 20: 'Twenty', 30: 'Thirty'}

NOTE : We cannot concatenate two dictionary using + operaor, it will give you an error : TypeError: unsupported operand type(s) for +: 'dict' and 'dict'
