Many programming interview questions have something to do with working with indexes. You may also be dealing with tasks at work that can have something to do with indexes.
One such task can be doing different splits and formattings of text files based on an index of a specific character.
Let us assume that you are asked to remove part of a string based on a certain index in a string.

Since you don’t have a predefined type for a variable in Python, you may notice a lot of bugs that can arise. As such, it is very important that you pay a lot of attention in cases when you have to make sure that you are using the correct type of variable.
This can also be the case when you expect a variable to be a number, but you get a string or any other type instead.

You have been doing math calculations since a very young age, from adding two numbers, to multiplying, dividing, and finding the square root of a number by hand.
In Python, you can also multiply a string with a number.
Yes, you read that right. You do not have to do something big, or fancy: You can just take a string and multiply it with any natural number.
You may be wondering, “What’s the result? I know what is 3 * 3, but I don’t know what’s going to be the result of 3 * ‘abc’?”

There are a lot of built-in methods that you can use to do a lot of manipulations with strings in Python.
You can convert them into lists, convert them from one case to another, or split them into partitions.
One such method is the opportunity to partition strings.

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
One of the main reasons why we as developers love programming in Ruby is because of the freedom that it gives to us. Having the autonomy to do something is one of the core pillars of motivation. In this article, we will briefly see how you can write a method that you can then call for each of your string objects, prepending an “a” or “an” before words.

It is very difficult to think about an application that does not have any string data type. Names, emails, object attributes, etc. are very common. Knowing their wide usages, it is obvious that we should at least learn the best practices about them. I recently learned about the difference between the efficiency of two similar string functions, which was a bit surprising and that made me write this article. Although both methods do the concatenation of strings, there is a big difference in their performance.
One of the core pillars of motivation is having the opportunity to use some form of autonomy at the work that you do. Ruby programming language allows you to do just that with a lot of its built-in features. It gives you the ability to override methods of basic built-in classes, methods and also attributes. One such attribute in which we will focus on this article is the ability to change the default new line delimiter. Continue reading
