A Python Program to Change the Value of a Key in a Nested Dictionary?
Code Explanation:
● Nested Dictionary Initialization:
A dictionary student is created with a key 'marks', which itself contains another dictionary (Math and Science scores).
● Access Nested Value:
student['marks']['Math'] is used to directly access the value of the 'Math' key inside the nested 'marks' dictionary.
● Update Value:
The value of 'Math' is updated from 85 to 95 using assignment.
● Final Dictionary:
The student dictionary now holds the updated value for 'Math' inside the nested dictionary.
● Output Display:
The updated dictionary is printed, showing the new value of 'Math'.
Program:
student = {
'name': 'John',
'marks': {
'Math': 85,
'Science': 90
}
}
student['marks']['Math'] = 95
print("Updated student dictionary:", student)
