Accessing & Traversing a Dictionary

☞Accessing elements in a dictionary :

  • To access its element, you have to use the [] square brackets along with the key to obtain its value.
Syntax : 
 
<dictionary_name> [<key>]
Example : 
 
#Accessing a dictionary element
D = {"Name" : "Anil", "Age" : 17, "Class" : "XII" }
print(D["Class"])
Output : 
 
XII

☞Traversing a dictionary :

  • It can be done using a for loop.
Example : 
#Traversing a dictionary
D = {"Name" : "Anil", "Age" : 17, "Class" : "XII" }
for i in D:                   #i will store key
    print(i,"=", D[i])
Output : 
 
Name = Anil
Age = 17
Class = XII
