Introduction to Data Analysis in Python
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,
# 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)
