In the realm of Python programming, there’s a special method that offers a glimpse into an object’s soul, revealing its identity and state in a unique way. Meet __repr__, a method that plays a crucial role in the world of object-oriented Python. In this short blog article, we’ll delve into the fascinating world of __repr__, exploring its purpose, usage, and why it’s an essential tool for any developer.
In Python, a tuple is an ordered and immutable collection of elements. Tuples are often used to store related pieces of information together, such as the x and y coordinates of a point, or the name and age of a person. Sometimes, we may need to count the number of times a particular element appears in a tuple. Python provides a built-in method called count() that makes it easy to accomplish this task. In this article, we will explore how to use the count() method to count the number of times an element appears in a tuple.
The count() method is a built-in method in Python that returns the number of times a specified element appears in a tuple. The method takes a single argument, which is the element to be counted. Here’s an example:
my_tuple = ('a', 1, 'f', 'a', 5, 'a')
print(my_tuple.count('a')) # 3
Most of the time you are adding elements into a list, or set, or a dictionary. However, there can also be cases when you just need to remove elements. Maybe a particular element, or even all elements at once.
If that is the case, then there is a quick method in Python that you can use to do that.

It is really hard to think about a real world project in which you are not going to have strings. As a result, having pre-existing methods for manipulating strings is really productive, as it saves you time. In today’s article, I want to emphasize a particular method in Ruby on Rails, that’s surprisingly not that much well known, which helps you with the whitespaces. Continue reading
