Where to Start Programming in Python

Python is a powerful and high-level object-oriented programming language created by Guido van Rossum. It has an easy-to-use syntax, making it an ideal language for those who want to learn programming for the first time. Here is an in-depth guide to getting started with Python, which also answers questions about why you should learn it and how to learn it. However, if you know other programming languages and want to get started with Python as quickly as possible, check out the Python Lessons for Beginners.

What is Python programming?

Before you start, get familiar with the language itself. Python is a general purpose language. It has applications in different areas: web development (like Django and Bottle), scientific and mathematical computing(Orange, SymPy, NumPy) for desktop GUIs(Pygame, Panda3D). The syntax of the language is simple, and the length of the code is relatively short. Working in Python is enjoyable because it allows you to solve a problem rather than focusing on complex syntax.

History of Python

Python is an old language created by Guido Van Rossum. Development began in the late 1980s, and the first version was released in February 1991. Why was Python created? In the late 1980s, Guido Van Rossum was working on the Amoeba group of operating systems. He wanted to use an interpreted language like ABC (ABC has a simple and easy to understand syntax) that could access Amoeba system calls. So he decided to create a scalable language. This led to the creation of a new language, which later had the name Python. Why Python was chosen No. It’s not named after a dangerous snake. Rossum was a fan of the comedy series in the late ’70s. The name “Python” was taken from the same show, Monty Python’s Flying Circus.

Python programming features

  1. A simple language that is easy and accessible to learn Python has a readable syntax. It is much easier to read and write programs in Python compared to other languages such as: C++, Java, C#. Python makes programming interesting and allows you to focus on the solution rather than the syntax. For beginners, a great choice is to start learning with Python.
  2. Free and open source You can freely use and distribute software written in Python, even for commercial use. Make changes to Python source code. There is a large community working on Python, constantly improving the language in each new version.
  3. Portability Move and run Python programs from one platform to another without any changes. The code works on virtually all platforms, including Windows, Mac OS X, and Linux.
  4. Scalable and embeddable Suppose that an application requires performance enhancement. You can easily combine snippets of C/C++ and other language code together with Python code. This will improve the performance of the application and also gives you the ability to write scripts that require more customization and time to create in other languages.
  5. A high-level, interpreted language Unlike C/C++, you don’t have to worry about complex tasks such as “garbage collection” or memory management. Likewise, when you run Python code, it automatically converts your code into a language that the computer understands. You don’t have to think about lower-level operations.
  6. Standard libraries for common tasks Python comes complete with a number of standard libraries, which makes life easier for the programmer because you don’t have to write all the code yourself. For example, to connect a MySQL database to a Web server, use the MySQLdb library, adding the import MySQLdb line. The standard libraries in Python have been tested and used by hundreds of people. So rest assured, they won’t break the application.
  7. Object-oriented In Python, everything is object-oriented. Object-oriented programming (OOP) helps you solve a complex problem intuitively. Break down complex tasks into small parts by creating objects.

Python applications

Web Apps Creating scalable Web Apps (Web Apps), using frameworks and CMS (Content Management System) created in Python. Popular platforms for creating Web Apps: Django, Flask, Pyramid, Plone, Django CMS. Websites such as Mozilla, Reddit, Instagram and PBS are written in Python. Scientific and numerical computing Python has many libraries for scientific and mathematical computing. There are libraries like SciPy and NumPy, which are used for general computing. And special libraries like: EarthPy for earth science, AstroPy for astronomy and so on. Also, the language is often used in machine learning, analysis and data mining. Software prototyping Python is slow compared to compiled languages such as C++ and Java. It is not a practical choice if resources are limited and maximum efficiency is needed. Nevertheless, Python is an excellent language for prototyping. Use Pygame (a game building library) to prototype a game to begin with. If you like the prototype, use C++ to make a real game. An easy language to learn programming Python is used to teach programming to children and beginners. It is a good language with many features and functions. Nevertheless, it is one of the easiest languages to learn because of its easy-to-use syntax.

4 reasons to choose Python as your first language

  1. Simple, elegant syntax Programming in Python is fun. It’s easier to understand and write code in Python. Why? The syntax feels natural and simple. Take this code as an example: a = 2
    b = 3
    sum = a + b
    print(sum)
    Even if you haven’t programmed before, you can easily figure out that this program adds two numbers and prints them out.
  2. Not too strict You don’t need to define the type of variable in Python. There is no need to add a “;” at the end of a line. Python forces you to follow methods for writing readable code (e.g., equal indentation). These little things can make it much easier for beginners to learn.
  3. Language expressiveness Python allows you to write programs with more functionality and fewer lines of code. Here’s a link to the source code for a Tic-tac-toe game with a GUI and a smart computer opponent of less than 500 lines of code. This is just an example. You’ll be surprised how much you can do with Python once you learn the basics of the language.
  4. Large community and support Python has a large community with lots of support. Lots of active forums online to help when questions arise. Here are some of them:

First Python program

Often a program called “Hello, World!” is used to demonstrate a programming language to newcomers. “Hello, World!” is a simple program that outputs “Hello, World!” Python is one of the easiest languages to learn and creating a “Hello, World!” program is just as simple, type print("Hello, World!"). So, we’ll write another program.

A program to add two numbers


# Add up two numbers
num1 = 3
num2 = 5
sum = num1 + num2
print(sum)

How does this program work?

Line 1: # Add two numbers A line beginning with # in Python programming is a comment. Comments are used to describe the purpose of a line of code. It helps you, as well as other programmers, to understand the meaning of the code. They are ignored by compilers and interpreters. Line 2: num1 = 3 Here, num1 is a variable. You can store the value in a variable. In this case, 3 is stored in a variable. Line 3: num2 = 5 Similarly, 5 is stored in the variable num2. Line 4: sum = num1 + num2 The variable num2 is added to num1 using the + operator. The result of the addition is stored in another variable sum. Line 5: print(sum) The print() function prints the result. In our case, it prints 8.

Important things to keep in mind.

To represent an instruction in Python, a new line (enter) is used. Using “;” at the end of the statement is not required (unlike C/C++, JavaScript, and PHP). Instead of curly braces { }, indents (4 spaces) are used to jump to a new block.
