Getting Started with Python

By: Fabrizio Romano, Benjamin Baka, Dusty Phillips

Overview of this book

This Learning Path helps you get comfortable with the world of Python. It starts with a thorough and practical introduction to Python. You’ll quickly start writing programs, building websites, and working with data by harnessing Python's renowned data science libraries. With the power of linked lists, binary searches, and sorting algorithms, you'll easily create complex data structures, such as graphs, stacks, and queues. After understanding cooperative inheritance, you'll expertly raise, handle, and manipulate exceptions. You will effortlessly integrate the object-oriented and not-so-object-oriented aspects of Python, and create maintainable applications using higher level design patterns. Once you’ve covered core topics, you’ll understand the joy of unit testing and just how easy it is to create unit tests. By the end of this Learning Path, you will have built components that are easy to understand, debug, and can be used across different applications. This Learning Path includes content from the following Packt products: • Learn Python Programming - Second Edition by Fabrizio Romano • Python Data Structures and Algorithms by Benjamin Baka • Python 3 Object-Oriented Programming by Dusty Phillips

Case study


Let's try to tie everything we've learned together with a larger example. We'll be developing an automated grading system for programming assignments, similar to that employed at Dataquest or Coursera. The system will need to provide a simple class-based interface for course writers to create their assignments and should give a useful error message if it does not fulfill that interface. The writers need to be able to supply their lesson content and to write custom answer checking code to make sure their students got the answer right. It will also be nice for them to have access to the students' names to make the content seem a little friendlier.

The grader itself will need to keep track of which assignment the student is currently working on. A student might make several attempts at an assignment before they get it right. We want to keep track of the number of attempts so the course authors can improve the content of the more difficult lessons.

Let's start by defining the interface...
