Using Modules

Libraries that you will use provide creating objects of new types with new properties, methods, attributes. Each library has specific documentation with explanations on methods/attrbites/classes provided. Let's remind what methods and objects are.

A method is a function that 'belongs to' an object.

An object is simply a collection of data (variables) and methods (functions) that act on those data.

Some libraries may also export constants - values that don't change during a program's execution. For example,


              
12345678910

            
# Importing library
from datetime import date
# Create new 'date' object
d = date(2022, 10, 10)
# Applying method to object
print(d.isoformat())
# Object attribute
print(d.month)
# Library constant
print(datetime.UTC)
copy

Var allt tydligt?

Hur kan vi förbättra det?
