Software Development From A to Z - OOP, UML, Agile and more

Let's talk about some of the most widespread misconceptions about becoming/being a software developer.

In this episode, I’d like to introduce the most frequent activities involved in the course of developing software.

Time to test your knowledge.

In this clip, I am going to talk about software development methodologies: what they are, and why are they so important.

Let's see what are the benefits and drawbacks of the Waterfall model.

In this clip, I am going to introduce the Agile model. This methodology is praised for providing fast response to changes, continuous improvement and early delivery of working software.

The Agile development methodology has become very popular. Yet, it does not come without issues. In this episode, we are going to analyze both its pros and cons.

In this clip, I am going to introduce Scrum, which is a way to organize team work around Agile principles.

Scrum organizes work in short, sustainable bursts of activity called sprints. In this episode, I am going to provide an overview of how work is managed within a sprint.

Each Scrum sprint starts with planning.

The "Daily Scrum" or standup is a daily ritual for scrum teams.

In this video, I talk about the two closing Scrum ceremonies: the review and the retrospective. I'll give you a real-life example towards the end of this lecture.

The Kanban system was first used by Toyota to improve the efficiency of mass-producing cars. As it turned out, Kanban can be applied also to creating software products - I'll explain how in this episode.

Kanban uses a big board to visualize pending work and the current capacity assigned to the given development phase. Let's have a look at the ways you can implement basic and more advanced Kanban boards.

Test your knowledge about Agile Frameworks

A funny and straightforward explanation of what coding is.

What's a programming language? How does the computer understand the code we write? In this lecture, I clarify these and many other topics.

In this lecture, we check if you have the right Python version on your machine, and I show you how to install Python 3.x if necessary.

In this lecture, you learn how to use the interactive Python language shell, also known as REPL (Read-Evaluate-Print-Loop).

In this video, we talk about code editors and IDEs. I also show you how to install Visual Studio Code, the IDE we'll be using to implement all the Python projects in this course.

Download the Python exercise files the instructor uses to teach the course.

In this video, we create a program that waits for user input and produces the output based on what the user entered.

I talk about the importance of code comments and explains how to include inline explanations in our Python programs.

In this video, we take a closer look at variables. I show you how to declare and use variables through coding examples. We'll also talk about the importance of adhering to naming rules.

Besides strings, numbers are the most common kind of values in computer programs. In this lecture, we discuss how to use numeric values in your Python programs.

In this lecture, we introduce the basic arithmetic operations: addition, subtraction, multiplication, and division.

We’ve seen how to define string literals, now let’s see some more advanced examples of using and managing text in our programs.

Although the Boolean type can only represent two values, True and False, it has a crucial role in programming. So, let's have a closer look at it.

In our programs, we need to have logic that only executes if specific conditions are true. The following lectures will introduce you to conditional code. I'll show you how to write effective and elegant programs using conditions, and comparison and logical operators.

In this video, I introduce the concept of code blocks.

Let's see what operators can we use in conditional statements.

As you write more complex programs, you’ll notice that a pair of if-else statements is rarely enough. In this video, we're going to use multiple conditions using the elif keyword. I'll also show you how to implement nested conditional code.

Let me show you how to check for another condition after a condition evaluates to true.

We can use logical operators to evaluate multiple conditions. In this lecture, I show you how to replace nested if statements with a more succinct alternative.

In this section, we dive into functions. Functions allow us to write code and reuse it anywhere in our programs. But why is reusability so important? I'm going to answer this and many other questions, too.

In this lecture, I show you how to create functions to wrap the code that we want to reuse.

Now that you know how to write a function, it's time to learn how to use it.

Starting with Python 3, we can inform the caller about the expected argument and return type of a function.

In this lecture, we talk about the scope of variables. We address questions such as "Can I access a variable that's defined within a function?" and more.

We're going to implement an application that calculates the area of various shapes.

Let's test the Area Calculator Demo we just built.

In this lecture, we enhance the Area Calculator demo further by encapsulating the conditional logic into a dedicated function.

Section Challenge

As an exercise, enhance the app with the option to calculate the area of a rhombus.

Hints for chapter challenge.

Solution for the chapter challenge.

The while statement allows us to repeat execution until an expression evaluates to false. In this lecture, I'm going to show you how to implement the while loop in Python.

Let's have a look at infinite loops and how to avoid them.

Often, we need to execute a block of code a number of times, then exit. The for loop provides this type of functionality.

You already know how to use the break statement. In this lecture, I introduce a second statement that can be used to control loops.

In this video, we refactor the Login program using the for-in loop.
