What is Python?
We’ll be starting from scratch. Hence, there’s no need to worry if you have no prior experience with Python or coding in general.
So, without further ado, let’s get started by learning what Python is.
The nature of the language
Developed in 1990, Python is one of the most popular general-purpose programming languages in modern times.
The term “general-purpose” simply means that Python can be used for a variety of applications and does not focus on any one aspect of programming.
Python falls under the category of high-level, interpreted languages. A high-level language is one which cannot be understood directly by our machine. There is a certain degree of abstraction in its syntax. Machines are generally designed to read machine code, but high-level syntax cannot be directly converted to machine code.
As a result, it must first be converted to bytecode which is then converted to machine code before the program can be executed.
Python is an interpreted language because, during execution, each line is interpreted to the machine language on-the-go.
However, if we take the example of C++, the code needs to be compiled into an executable first, and then it can be executed. In Python, we can skip this compilation step (Python does it for us behind the scenes) and directly run the code.
One of the biggest reasons for Python’s rapid growth is the simplicity of its syntax. The language reads almost like plain English, making it easy to write complex programs.
Since it doesn’t have much of a learning curve, Python is a very good entry point into the world of programming for beginners.
Apart from the ease of learning, Python is a very efficient language which is used in almost every sphere of modern computing.
This makes a strong case for learning Python, even for non-programmers.
Some of Python’s main applications are highlighted below:
Python has had several major updates in the past. Python 2.7 was widely used for a very long time, even after the release of newer versions.
However, Python 2.7 has been deprecated as of January 01 2020, and replaced completely by
3.xx versions, known as Python 3. The differences between Python 2.7 and Python 3 are minute, but important nonetheless.
To keep up with the latest technologies, we’ll be using Python 3.
We will be able to write and execute Python code right here.
