Python: A Complete Beginners Guide to Learning, Programming & Certifications in Python

“Python is now the second most popular language in the world overtaking Java.”- Stack Overflow State of Octoverse 2019 

Python is an object-oriented, high-level programming language with interpreted dynamic semantics. In simple terms, we can say, Python is a programming language that is used to develop software on the web and mobile app. Due to its high-level built-in data structures, dynamic typing and dynamic binding, it is extremely important for Rapid Application Development. It is also used as a scripting or glue language to connect existing components together.

Python is one of the popular languages which is used for general-purpose programming. Created by a Dutch programmer named Guido van Rossum, it was first released on February 20, 1991. This programming language was named after the BBC television show Monty Python’s Flying Circus.

Compared to other programming languages, Python is relatively easy to learn. It allows a programmer to write the programs and instructions using fewer lines of codes. Due to its unique syntax, Python reduces the cost of program maintenance and development.

This also allows the teams to work collaboratively without facing any barriers. Even developers find it easy to read and translate Python code than other languages such as C++, Java etc.

In addition to this, Python supports the use of modules and packages. This means the program modularity and code can be reused across many projects. It also gives the user the liberty to write an object-oriented program on both a small and large scale.

Here are some of the basic features of Python:

1. Object-Oriented

Python is built around objects that combine data and functionality, supporting object-oriented programming.

2. Interpreted

Python is an interpreted language hence it can be run from the source code without the use of separate compilation and execution steps.

3. Simple and Easy to Learn

It is extremely simple to learn as compared to other programming languages. Its easy-to-use syntax makes it the most chosen option for people who are learning programming for the first time.

4. High-Level Language

A language is called high-level depending on how many layers it is away from the machine code. Python is considered a high-level programming language as it is highly abstracted from the Assembly Language used to provide instructions to the CPU.

5. Extensive Library

Python library is extensively huge offering a wide range of facilities like regular expressions, databases, unit testing, web browsers, email, XML, HTML etc.

Python Certifications

Every institute, upon completing a Python Course, will give a completion certificate. The python certification course is a package of several classes and chapters. It’s related fundamentals, core and advanced Python concepts, web applications using Python in scripting or programming a requirement.

There are several levels of Python certification that one must attain to become an expert. Some certifications in this language are:

• Python programmer (PCEP)
• Certified Associate in Python Programming (PCAP) 
• Certified Professional in Python Programming (PCPP) 

Having a Python certificate can open doors to many opportunities giving your career a boost.

Python Programming

The Python course includes 36 courses and around 13 projects in total. It will cover core topics like –

• Python Fundamentals
• Linux System Administration with Python
• Cryptography
• Django Unchained with Python
• Python GUI Programming using Tkinter
• Rest API with Flask and Python
• Python Pyramid Jupyter-IPython Notebook
• Violent Python

If you are a beginner, you can start with the beginners level and then go to an intermediate level. So below are the steps on how to learn Python Language step by step.

Beginner’s Level:

If you know the basics of Python, then you can skip this level to Level 1. If not, then you’ll get to learn the fundamental concepts such as variables, data types, operations, functions, conditionals, and loops.

Level 1 Object-oriented Programming: 

Also known as OOP, Object-oriented programming is necessary for a learner to understand how to structure and design the code.

• Concept of OOP
• Python problem Solving using OOP

Level 2 Concurrent and Parallel Programming

• Mutual Exclusion
• Locks
• Deadlocks
• Race Condition

You’ll also need to learn about threading, queue, and multiprocessing Python modules to help you write parallel programs.

Level 3 Socket Programming: 

Socket Programming will help you write code that will allow you to communicate with other machines over a network.

• Write an Echo Program
• Learn HTTP
• Networking tools like ping, netstat, Wireshark, tcpdump

Level 4 Data Structures and Algorithms

Level 5 Prepare for Python Coding interview

Level 6 Advanced Python: You’ll be studying new concepts like –

• Higher-order Functions
• Control Flow
• Metaprogramming

Apart from the steps mentioned above, you can also learn about Python Libraries, Frameworks and Python Implementation (CPython) to get a detailed and deep understanding of the subject.

Python Course Fees

The fee structure for Python courses differs from one institute to another and from city to city. However, the average price in India can range from 15,000 to 12,000; this includes certification as well. The course fee will also depend on the duration, medium of learning – online or classroom etc.

Uses of Python

Python is an interpreted language that useful for building computational engines, websites, automation tools, machine learning, process text, display images and numbers, save data, solve scientific equations and all backend processes etc. This language can also be referred to as a “scripting language” since initially it was meant to be used for minor projects.

Today, a majority of web applications and platforms like Google’s search engine, New York Stock Exchange (NYSE), YouTube, etc., rely on Python. NASA also uses Python while programming their equipment and space machinery.
