One of the first commands that you have probably written when you started your journey learning programming was printing a “Hello World” statement:
Did you know that you can print more than just a “Hello World” or other things in a single line?

Let’s assume that you want to find the difference between 2 numbers. As you probably remember from school, the difference is not commutative, meaning that:
a — b != b -aContinue reading
Dictionaries represent a commonly used data structure in many scenarios. You may also have cases when you need to merge 2 dictionaries, for example, given that we have 2 equal keys, we want to get the value of the second dictionary.

One of the most common ways to introduce someone to programming is by starting with printing Hello World and then showing them how to do math operations using simple coding instructions.

Lists are pretty much widely used throughout every project that you can think of. Tuples, on the other hand, are not that common, but both of them have something in common that you can use right away.
You can use the same method for both of them to find indexes of certain elements.

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’?”

In a lot of projects, there are usually a lot of symbols-like constants that are used throughout the application.
They could be currency symbols, weather types, clothes sizes, etc.

One of the first things that you learn when you start to program is learning how to declare a variable and assign to it a value.
For example, you are told to assign a string and then print it in a console:
Now, if we want to assign another variable in there, our intuition can be to just add a new line, and assign it there:
Lists represent one of the most used data structures in any Python script. One of the reasons why I like programming in Python is that I get to reach a result quite quickly.
One such thing is the opportunity to easily and quite simply access their elements quite flexibly.
With flexibility, I mean, having the opportunity to choose only the elements that we want.

One of the main uses of methods in any programming language is the opportunity to simply implement a functionality once and then use it as many times as you need.
In a lot of cases, you are supposed to call these functions with actual parameters that are then expected to be used inside the method.
