Let's build a dictionary named student.


              
12

            
student = {'first name': 'Ann', 'last name': 'Elliot', 'city': 'New York'}
print(student)
copy

Here's how you can add a key-value pair to a dictionary.


              
123

            
student = {'first name': 'Ann', 'last name': 'Elliot', 'city': 'New York'}
student['country'] = 'USA'
print(student)
copy

The student dictionary includes these pairs:

KeyValue
'first name''Ann'
'last name''Elliot'
'city''New York'
'country''USA'

Note

Single ' ' and double " " quotes in Python are interchangeable and equivalent.

Task

  1. Construct the following dictionary: 'name': 'Max', 'position': 'data scientist', 'level': 'junior';
  2. To the existing dictionary, append a new key named experience (as a string) with the value of 1.
