An Introduction to Python

Python is an interpreted, high-level programming language that was first released in 1991. With an emphasis on code readability, it enabled programmers to use fewer lines of code for the same concept. This key feature triggered a wave of universal usage and ultimately, global popularity.

It supports various programming paradigms, including but not limited to object-oriented, functional and procedural programming. This flexibility has rendered it useful for writing code in different ways, from simpler applications to complex ones.

But what makes it such a popular language? The next section explores the key features of Python that contribute tremendously in making it the ultimate language to learn.

Key Features of Python

Here are a few features that give this language such an edge over its competitors.

1. Easy to Code & Read

In spite of being a high-level language, it is pretty easy to learn, code and read. Within a few days of working on it, anyone can understand the basics. Of course, becoming a professional with complete command will take some time. Since its syntax is like simple English, even beginners do not find it very difficult to get started.

2. Robust Standard Library

Its extensive robust library is open to all to use. This gives programmers the aid of not having to write a code for every little thing, as is needed in other languages. These libraries support many functionalities like databases, expressions, image manipulation, unit testing, etc.

3. Portable

A code written in Python can be easily used on different machines. Thus, a code written on Linux can later be run on Windows or Mac without any issues. This saves a lot of time.

4. Dynamically Typed

It is dynamically typed, which basically means that the data type of the variable does not have to be declared upon creation. Python interpreter automatically infers the types, rendering the code easier to work with and highly flexible.

5. Expressive

Only a few lines of code is enough to perform complex tasks in Python. This makes it a highly expressive language.

How To Learn Python- 6 Steps to Succeed

These six steps are the only ones needed to answer all questions around how to learn Python from scratch. As a beginner, it is imperative to consider even the smallest factors and make it a learning step.

Learn Python Basics

The first thing to do is begin learning Python basics.

  • Understand the Basics

Since Python's focus is on code readability, it enables programmers to express concepts in a limited line of code. Begin by understanding the basic concepts such as data types, operators and variables.

  • Install Python & Set up the Environment

Prior to commencing coding in Python, it is important to install it and set up a development environment. It is easily downloadable from its official website.

  • Understand the Syntax & Structure

To understand the syntax and the structure of this language, begin by writing the most basic program. This could be the common ‘Hello, World!' script.

  • Functions

In Python, functions refer to blocks of reusable code that are in charge of performing a specific task. Programmers can either use the built-in functions or define their own.

  • Control Flow

Control flow statements give a program the ability to repeat actions and make decisions. Some most common ones are while-loops, if-statements- and for-loops.

  • Python Data Structures

Sets, dictionaries, tuples and lists are a few built-in data structures that come handy for storing and manipulating data in the programs. Learning about them is important.

Master the Intermediate Concepts

Once the basics are covered, it's time to move to mastering the intermediate concepts. These will lay down the path for more advanced understanding.

  • Object-Oriented Programming

Object-oriented programming (OOP) is a paradigm that enables programmers to structure the code around classes and objects. It is imperative to gain knowledge of OOP concepts like inheritance, classes, polymorphism and objects. All these will facilitate a more efficient and organized code writing.

  • Working with Libraries

Its plenty of libraries are the reason behind this language's popularity. Getting a working understanding of the top ones is important. Matplotlib is great for data visualization, NumPy is great for numerical computing and Pandas is apt for data manipulation.

  • Error Handling & Exceptions

There are many tools in Python that aid in handling exceptions and errors in the code. The key here is to learn to use except/try blocks & raise exceptions to write robust programs.

Practice Till You Ace it

Since Python is not something that has a theoretical use, one must learn it by working on it. Actively using it is the most effective way to gain in-depth knowledge in this language. Practice will lead to gaining good knowledge of the syntax, libraries and frameworks.

  • Work on Challenging Projects

There are many different projects to work upon as a beginner. It could be a simple data analysis project, a script to automate a routine task or a web application.

  • Apply Learnings to Personal Projects

It is also a good idea to recreate any existing tools or projects that stand out in interest or usefulness. This drives greater learning and implementation.

  • Attend Webinars & Sessions

Webinars and sessions are a great way of learning from different professionals with hands-on experience. They share their learnings and valuable advice that comes in handy for beginners.

Build a Portfolio

Working on different projects is not only useful to hone new skills and polish the existing ones. These projects are great additions to the portfolio and play a huge role in expanding it. This portfolio should be a clear depiction of the interests, skills and capabilities that stand out the most.

Keep Learning & Reinventing Skills

Learning should be a non-stop process, just like Python's growth. Upon mastering the basics, move on to the intermediate-level skills and then move on to advanced level skills. By the time this is done, some new technologies or tools will sprout. Or changes to the existing ones will happen.

Keep reinventing and polishing skills to stay in the run for the top jobs in top industries.

Learn from Professionals

One of the best things to do for career growth is to learn from professionals. The best way today is to enroll in an online course that gives the space to learn at one's own pace. There are different courses to meet the needs of different experience levels.
