bookExtraction of Information

Let's build a dictionary called student.


              
12

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

This dictionary includes three key-value pairs:

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

In the dictionary, you can retrieve an item using its key. Here's an example.


              
123

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

In the code provided, Python searches for the value associated with the 'city' key in the student dictionary and assigns this value to the city_of_student variable.

Time to get hands-on!
