#3 Python Tutorial for Beginners | Getting Started with Python
Introduction to Python Programming
In this lesson, we will be talking about Python programming. In the previous lessons, we discussed what Python
is and how to install it on your machine. Now, it's time to dive into the actual coding.
Step 1: Opening Your IDE
Before we start with the actual code, we have to ask ourselves, why do we code? We live in a world where
everything is done with computers. If we want to talk to our computer, we need to understand their language,
which is binary code. However, it's not exactly possible to talk to a computer in binary code. So, we created
programming languages, like Python, to bridge the gap between human and computer languages.
To start coding in Python, we need to open our Integrated Development Environment (IDE). In this tutorial, we
will be using IDLE, which is one of the easiest IDEs to use.
Basic Operations in Python
Let's start with some basic operations. We will be using the Python interpreter to execute our code. We will try
out addition, subtraction, multiplication, and division.
Addition: To add two numbers, we use the '+' symbol. For example, 2+3=5.
Subtraction: To subtract two numbers, we use the '-' symbol. For example, 9-8=1.
Multiplication: To multiply two numbers, we use the '*' symbol. For example, 4*6=24.
Division: To divide two numbers, we use the '/' symbol. For example, 8/4=2.0. Note that this gives us a float
value.
We can also use brackets to group our operations. For example, (8+9)-10=7.
We can also use exponentiation to find the power of a number. To do this, we use the double asterisk '**'
symbol. For example, 2**3=8.
