Python get() method Vs dict [key] to Access Elements

get() method returns a default value if the key is missing.

However, if the key is not found when you use dict[key], KeyError exception is raised.

person = {}
 
# Using get() results in None
print('Salary: ', person.get('salary'))
 
 
# Using [] results in KeyError
print(person['salary'])

Output:

Salary:  None
Traceback (most recent call last):
  File "", line 7, in 
    print(person['salary'])
KeyError: 'salary'
