Python For Beginners: Learn To Code Python From Scratch

by | Feb 6, 2024


Python stands as a high-level, interpreted programming language, distinguished by its focus on code readability. Created by Guido van Rossum and released in 1991, Python has since evolved into a versatile tool for developers.

Designed to enable the expression of concepts in fewer lines of code compared to languages like C++ or Java, Python simplifies the programming experience without sacrificing power. It supports multiple programming paradigms, such as procedural, object-oriented, and functional programming. This flexibility allows programmers to approach problems in a variety of ways — whether by providing the computer with a procedural to-do list, modelling digital concepts through object-oriented programming, or approaching code as a series of functional equations. This blend of simplicity, versatility, and power makes Python an ideal starting point for beginners eager to learn to code from scratch and explore the basics of programming. 

The Rising Popularity of Python

Python’s ascent to the top of the TIOBE index in January 2024 cements its position as the most popular programming language, a testament to its widespread acceptance and diverse applications. Its appeal lies in a combination of factors: simplicity, versatility, and an extensive range of applications — qualities that make it particularly well-suited for fields as demanding and intricate as data science. Python’s straightforward syntax and focus on readability reduce the learning curve for beginners, making it easier for those new to programming to grasp key concepts and start building their own projects.

Strengths of Python

Several core features contribute to Python’s status as a preferred language for a wide array of programming needs:

  • Readability: Python’s syntax is designed to be intuitive and clear, closely mirroring the structure of the English language. This readability not only makes it accessible for beginners to learn but also simplifies the process of coding and debugging for seasoned programmers.
  • Ease of Learning: The straightforward nature of Python’s syntax means that beginners can quickly grasp the basics of programming, making the initial steps of learning a smoother journey.
  • Versatility: Python’s applicability spans across various domains, from web development and task automation to data analysis and machine learning, offering beginners a broad field of opportunities to explore and specialise in.
  • Rich Library Support: Python boasts a comprehensive standard library and an extensive collection of third-party packages, enabling developers to leverage pre-written code for a multitude of tasks, thereby accelerating the development process.
  • Platform Independence: Python’s cross-platform compatibility ensures that code written on one operating system can be executed on others without modification, facilitating collaboration in diverse development environments.
  • Interpreted Nature: As an interpreted language, Python executes code line by line, which simplifies debugging and allows for the testing of small code segments independently, enhancing the learning experience for beginners.
  • Open Source: Python’s open-source licence encourages a vibrant community of developers to contribute to its development, enriching the Python ecosystem with a wide array of libraries and tools.
  • Dynamic Typing: The dynamic typing feature of Python means that variable data types are determined at runtime, making the code more flexible and reducing the need for boilerplate code declarations.

R 1-3 months 4-12 months
Julia 1-3 months 4-12 months

*Note: These timelines are indicative and depend on individual learning pace and dedication.

Understanding the Basics of Python

This segment will guide you through the fundamental concepts and syntax of Python, highlighting its accessibility to beginners as compared to other programming languages.

Overview of Python Fundamentals

One of Python’s hallmark features is its use of indentation to define code blocks, eschewing the curly braces found in languages like C or Java. This unique characteristic not only enhances readability but also emphasises the importance of consistent indentation in Python programming.

Variables in Python are straightforward to declare, requiring no specific keywords. They serve as containers for storing data values, which can be referenced and manipulated throughout your programme. Python supports various data types, such as integers, floats, strings, lists, dictionaries, and more, each with its own set of methods and properties.

Python’s extensive standard library, along with its support for object-oriented programming, error and exception handling, underscores its flexibility and robustness. The language’s built-in functions and modules simplify common programming tasks, while its dynamic typing system eases the development process.

Basic Concepts for Python Beginners

Concept Description
Variable A name assigned to a value, using the = operator. Variables can store data of any type.
Data Types Includes integers, floats, strings, lists, tuples, dictionaries, Booleans, and None.
Operators Supports arithmetic, comparison, logical, assignment, membership, and identity operators.
Conditional Statements Used to execute code blocks based on certain conditions, employing if, elif, and else keywords.
Loops For iterating over sequences (for loops) or executing code until a condition changes (while loops).
Functions Blocks of code designed to perform a specific task, defined using the def keyword.
Libraries Collections of pre-written code for specific tasks, such as NumPy for numerical computations.
Classes and Objects Python supports object-oriented programming, allowing for the definition of classes and instantiation of objects.


Setting Up Your Python Environment

Setting up a proper Python development environment is crucial for both beginners learning Python and seasoned developers working on complex projects. A well-configured environment ensures that your projects are isolated, manageable, and replicable, avoiding conflicts between different projects or system-wide installations. This guide will walk you through the basics of setting up your Python environment, focusing on the use of virtual environments, which are essential for managing project-specific dependencies without affecting your global Python setup.

Virtual Environments: The Why and How

A virtual environment in Python is a self-contained directory that holds a specific version of the Python interpreter along with a set of libraries. When activated, it allows you to work on a project without interfering with other projects or the system-wide Python installation. This isolation is particularly useful when projects require different versions of the same library, preventing dependency conflicts.

Creating a Virtual Environment with Venv

Python 3.3 and newer versions include venv, a module that creates virtual environments. To set up a new virtual environment, you’ll first need to decide on a location for your project. Then, open your terminal, navigate to your project directory, and execute the following command:

python3 -m venv myenv

Replace myenv with your preferred name for the virtual environment. This command creates a new directory in your project folder, containing a copy of the Python interpreter, a dedicated pip installer, and a standard set of libraries.

Activating the Virtual Environment

To start using the virtual environment, you must activate it. Activation adjusts your shell’s PATH to ensure commands like python and pip specifically use the versions in your virtual environment, rather than the system-wide versions.

  • On macOS and Linux: source myenv/bin/activate
  • On Windows CMD: myenv\Scripts\activate.bat

Once activated, your terminal will typically show the name of the virtual environment, indicating that it is currently in use.

Managing Dependencies

With your virtual environment activated, any Python packages you install using pip will be placed in the virtual environment’s directory, isolated from the global Python installation. To install a new package:

pip install package_name

To keep track of your project’s dependencies, you can generate a requirements.txt file, which lists all the installed packages and their versions:

pip freeze > requirements.txt

This file can be used to replicate the environment elsewhere by running:

pip install -r requirements.txt

Deactivating the Virtual Environment

When you’re done working in the virtual environment, you can deactivate it by simply running:


This command returns your terminal to its normal state, using the system-wide Python and PATH settings.
