Python Dictionary 9

Delete elements from a Nested Dictionary

In Python, we use “del” statement to delete elements from nested dictionary.

Example : How to delete elements from a nested dictionary?

employee = {1: {‘name’: ‘Amit’, ‘age’: ’27’, ‘sex’: ‘Male’},
2: {‘name’: ‘Soniya’, ‘age’: ’22’, ‘sex’: ‘Female’},
3: {‘name’: ‘Neha’, ‘age’: ’24’, ‘sex’: ‘Female’, ‘married’: ‘No’},
4: {‘name’: ‘Sumit’, ‘age’: ’29’, ‘sex’: ‘Male’, ‘married’: ‘Yes’}}

del employee[3][‘married’]
del employee[4][‘married’]

print(employee[3])
print(employee[4])

When we run above program, it will output:

{‘name’: ‘Neha’, ‘age’: ’24’, ‘sex’: ‘Female’}
{‘name’: ‘Sumit’, ‘age’: ’29’, ‘sex’: ‘Male’}

In the above program, we delete the key:value pairs of married from internal dictionary 3 and 4. Then, we print the employee[3] and employee[4] to confirm changes.

#employee details
employee = {1: {'name': 'Amit', 'age': '27', 'sex': 'Male'},
          2: {'name': 'Soniya', 'age': '22', 'sex': 'Female'},
          3: {'name': 'Neha', 'age': '24', 'sex': 'Female', 'married': 'No'},
          4: {'name': 'Sumit', 'age': '29', 'sex': 'Male', 'married': 'Yes'}}

del employee[3]['married']
del employee[4]['married']

print(employee[3])
print(employee[4])

Output:

{'name': 'Neha', 'age': '24', 'sex': 'Female'}
{'name': 'Sumit', 'age': '29', 'sex': 'Male'}

Example : How to delete dictionary from a nested dictionary?

employee = {1: {‘name’: ‘Amit’, ‘age’: ’27’, ‘sex’: ‘Male’},
2: {‘name’: ‘Soniya’, ‘age’: ’22’, ‘sex’: ‘Female’},
3: {‘name’: ‘Neha’, ‘age’: ’24’, ‘sex’: ‘Female’},
4: {‘name’: ‘Sumit’, ‘age’: ’29’, ‘sex’: ‘Male’}}

del employee[3], employee[4]

print(people)

When we run above program, it will output:

{1: {‘name’: ‘Amit’, ‘age’: ’27’, ‘sex’: ‘Male’}, 2: {‘name’: ‘Soniya’, ‘age’: ’22’, ‘sex’: ‘Female’}}

In the above program, we delete both the internal dictionary 3 and 4 using delfrom the nested dictionary employee. Then, we print the nested dictionary employee to confirm changes.

#employee details
employee = {1: {'name': 'Amit', 'age': '27', 'sex': 'Male'},
          2: {'name': 'Soniya', 'age': '22', 'sex': 'Female'},
          3: {'name': 'Neha', 'age': '24', 'sex': 'Female'},
          4: {'name': 'Sumit', 'age': '29', 'sex': 'Male'}}

del employee[3], employee[4]

print(employee)

Output:

{1: {'name': 'Amit', 'age': '27', 'sex': 'Male'}, 2: {'name': 'Soniya', 'age': '22', 'sex': 'Female'}}
