Python Dictionary keys Example 2

In this program, we are going to insert a new value into the dictionary and print keys. Next, we updated a value and displayed the dictionary keys.

emp = {'name': 'Kevin', 'age': 25 , 'job': 'HR'}
print("Dictionary: ", emp)

# Print Keys
print("\nDictionary Keys: ", emp.keys())

# Print Keys
emp['age'] = 27
print("\nDictionary Keys: ", emp.keys())

# Print Keys
emp['Sal'] = 725000
print("\nDictionary Keys: ", emp.keys())

Dictionary:  {'name': 'Kevin', 'age': 25, 'job': 'HR'}

Dictionary Keys:  dict_keys(['name', 'age', 'job'])

Dictionary Keys:  dict_keys(['name', 'age', 'job'])

Dictionary Keys:  dict_keys(['name', 'age', 'job', 'Sal'])
