PythonServer Side ProgrammingProgramming Taking advantage of the for loop and range function in python, we can draw a variety of for pyramid structures. The key to the approach is designing the appropriate for loop which will leave both vertical and horizontal space for the position of the ...
I have intended to write a short e-book aboutdesign patternsusing the python programming language. This is inspired by the aptly titledDesign Patterns: Elements of Reusable Object-Oriented Softwareby Erich Gamma, Richard Helm, Ralph Johnson and John Vlissides who are collectively known as the Gang...

Python - Anti-Patterns These are common programming practices that, while not necessarily wrong, often lead to less efficient, less readable, and less maintainable code. By understanding these pitfalls, you can write cleaner, more efficient code for your Python applications....
Design patterns encourage clean programming. In this course, Jungwoo Ryoo—a professor of information sciences and technology—guides you through several advanced design patterns as applied to Python. Explore why—or why not—you may want to use design patterns in the first place. Step through some...
