To learn other useful string methods in Python, feel free to check this article. In this guide, we take a look at other common situations related to removing spaces from

The __qualname__ attribute means qualified name in Python. It gives you a dotted path to the name of the target object. Using __qualname__ is useful with nested structures, such as when you have a method inside a class. For example: The result of this is a full path to the attribute: __qualname__ vs __name__ in

To use a while loop to find the factorial of a number in Python: Here is how it looks in code: Let’s test that it works: Output: There you have it! To learn more about factorials and some alternative ways to calculate the factorial, please read along. What Is the Factorial of a Number in

In Python, a metaclass is a “class of a class”. It defines how a class itself is constructed. Whenever you create a Python class, a metaclass is invoked under the hood. This metaclass turns the class into a Python object. To truly understand what a metaclass is, you need to understand how classes work. In

The difference between the yield and the return statement in Python is: I’m sure this raises more questions than it answers. Let’s go through yield in Python in great detail. Our goal is to understand why and when should one use yield over the return statement in Python. Generators in Python Any function that yields

In Python, self refers to the class object itself. With self, you are able to access the attributes and methods of the class. For instance, this Fruit class assigns a custom name and color to itself upon creation. These can then be accessed by the info() method: Output: To understand how this works, let’s dive

To implement a progress bar in Python, write a function that takes its arguments the progress in percentages, and the width of the bar.
