print(“Name:”, student[‘name’])

print(“Age:”, student[‘age’])
print(“Grade:”, student[‘grade’])

• Elements of the dictionary are accessed using keys, and their values are printed.
Output:

TASK 2: Dictionary Operations
student = {
‘name’: ‘SreeHari’,
‘age’: 20,

‘grade’: ‘A’
}
# Modifying dictionary
student[‘age’] = 21

student[‘course’] = ‘Computer Science’
# Deleting a key-value pair
if’grade’in student:
del student[‘grade’]
# Iterating through dictionary items

for key, value instudent.items():
print(f”{key}: {value}”)
Explanation:
• The dictionary is modified by updating the ‘age’ and adding a new key ‘course’.
• A key-value pair (‘grade’) is deleted using the del keyword.

• A loop iterates through the dictionary items, printing each key-value pair.
