Setting Up Your Python Environment

The first step to learning Python development and building a solid career understands its environment and setup. With professional support and guidance, you can learn the step-by-step process of installing Python on Windows, Mac, and Linux.

We have discussed the best installation methods for each platform here to give you sound knowledge. Let’s dive in to learn more.

Install Python on Windows –

There are three ways you can install Python on Windows, they are –

Using the Microsoft Store

Microsoft has a community release of Python 3 in the Microsoft Store. It is the ideal way to install Python on Windows, as it handles the updates automatically and can be easily uninstalled.

  • To use this process, you have to open the Microsoft Store and search for Python
  • Then you have to pick the newest version and install it

With the official installer

You can also download the Python installer from the official website. This method does not provide automatic updates, so it is not the best. While using this installer, ensure that you mark the checkbox saying “Add Python to PATH.”

Inside WSL

If you are familiar with the Windows subsystem for Linux, you can install this option, too. It offers the benefits of Windows while using Linux, as it provides good hardware support.

Installation on macOS

In most versions of MacOS, Python distribution is already included. However, it comes in an older version, Python 2.7.

To install Python 3 on a Mac there are two ways –


First and foremost, I recommend looking into Homebrew. It allows you to install almost anything quickly. The added benefits:

Homebrew allows you to install almost every software required for Mac. The packages remain updated accordingly, and it is easy to upgrade to newer versions whenever needed.

However, you must be comfortable using a command-line shell to use Homebrew. If that’s entirely new for you, I recommend the following option for now: using the official installer.

Open the terminal application. You can find it in Applications > Utilities > Terminal.

Then you have to type the following command and press Enter

Code language: Bash (bash)


Official installer

You can also download an installer from the Python download website. It’s easy and functions like installing any other MacOS software. Like Windows, ensure that Python is added to your system’s PATH.

Install Python on Linux

There are various ways to install Python on Linux. First, you need to check if it is already installed. Most Linux distributions include Python, and some even include both Python 2 and Python 3.

You will see the version number if you enter the Python version on the command line. Like

Code language: Bash (bash)

2.7: $ Python –version will appear like Python 2.7.16.

If you try the same for the Python 3 version and get “command not found”, then you have to install Python 3.

But if it’s pre-installed, it will appear

Code language: Bash (bash)

$ python3 –version as Python 3.8.5.

Using a package manager

Depending on the Linux distribution, you can install Python with the default package manager, such as Yum, APT, etc. You must determine which package manager to use for your specific Linux distribution and how to use it.

Another option for Linux to install Python is Homebrew. The package manager for Mac also works on Linux.

Choose your IDE

An IDE, or Integrated Development Environment, is a software application that provides multiple facilities for software development. It incorporates different tools and features, such as debugging tools, a source code editor, project management tools, and more, into a single application, helping to streamline the development process.

Let’s learn about the popular Integrated Development Environments (IDEs)

  • PyCharm

PyCharm is cross-platform, as it is compatible with Windows, Linux, and macOS; being part of the Python IDE is essential for professional development. It is famous for its intelligent code completion, testing, and debugging features. It supports libraries and frameworks, thus making it an ideal choice for data science and web development. It also has a community edition, which is free and open source.

  • Jupyter Notebook

Jupyter Notebook is an open-source web application that allows you to create and share documents containing codes, texts, and visualizations. It has a user-friendly interface and supports features like interactive widgets, real-time data visualizations, and collaborations. It can also integrate with various programming languages, such as Python, PHP, R, etc.

  • Visual Studio Code

Visual Studio Code, or VS Code, is a lightweight and versatile IDE well-known among professional Python developers. It offers a varied set of features, including code completion, debugging, and source control integration. It also has a wide collection of extensions and plugins, which enhance the overall coding experience.

New Learners- Get informed about Python Basics

Python is one of the most vital programming languages nowadays. Professional developers focus on implementing programs rather than writing complex ones, making Python the ideal solution due to its ease of readability and access.

  • Python Syntax and Basics

The syntax is how Python is written, mainly in the order and manner in which a line of code is constructed. It helps to determine how the various statements written in Python will be interpreted.

One of Python’s most essential factors is its syntax; it needs to be simple, readable, and concise. Even some of the other features, like decorators, iterators, or generators, if implemented in the right way, can make the code easy to understand and change.

  • Variables

A variable is a reserved memory location that is used to store data. It stores data, which can be changed during the program if required. In Python, naming a variable follows the same rule as identifiers.

The variable type in Python needs no specification as the language derives it independently. A variable gets created as soon as a value is assigned to it. One doesn’t need any additional commands to declare a variable in Python.

  • Data type

In statically typed languages like C or Java, defining the variable’s data type is not required. In dynamically typed languages like Python, the interpreter predicts the data type of the variable based on the type of value assigned to that variable.

A data type is defined as the classification of the types of values that can be assigned to variables. In Python, it is important to understand the different types of values that can be assigned to variables.

Python data types are categorized into two sections:

  • Mutable Data Types: In Python, data types where the value is assigned to the variable can be modified. Mutable data types include set, list, dictionary, and user-defined classes.
  • Immutable Data Types: In Python, immutable data types are those in which the value assigned to a variable can’t be changed. Examples of immutable data types in Python are int, decimal, float, tuple, bool, range, and string.

Write your first Python program

You need to learn the Python basics to start writing a Python program, like a basic “Hello, World!” script.

A simple script is a simple and complete first program for beginners, ideal for testing systems and programming environments.

For example, “Hello, World!” defines the basic syntax of the programming languages. This process helps you understand the syntax and structure of Python code.

The basics of this process are –

  • Python data structures

Python offers multiple built-in data structures, such as lists, tuples, sets, and dictionaries. These data structures store and control the data in programs. The Python course includes a section dedicated to data structures and algorithms in Python that covers a wide range of these aspects.

  • Control flow in Python

Control flow statements, like for-loops, if-statements, and while-loops, allow the program to make decisions and repeat actions. Implementing these statements helps develop a Python program.

  • Functions in Python

The functions in Python are blocks of reusable code that carry out a specific task. You can define your functions and write a Python program with built-in Python functions. With a beginner’s guide to Python, you can write reusable, complex and consistent tasks as required for the program.

What are Control Structures?

Control structures are crucial to programming. They enable you to specify the flow of execution in your code. In Python, there are various types of control structures, including conditions, loops, and calling functions. These are essential for making decisions and repeating tasks.

  • Conditional statements

Conditional statements help to change a program’s behaviour depending on whether some conditions are true or not. They are used in almost all programming languages and take the form of if or switch conditions.

  • “If”-statement

In Python, an if statement consists of the “if” word, followed by a condition and then a colon. The colon is required as it separates the header of the statement from the body. Indentations are essential in Python.

An improper indentation might result in errors that are difficult to solve. The condition after “if” has two possibilities. If it is true, then all the following statements will be executed. If the condition is false, the program will skip the lines of code associated with the if-statement and move on to whatever comes later.

  • “Else”-statement

Suppose you want one thing to happen when a condition turns out to be accurate and something different when it is false; this situation can be addressed using an if-else statement. This statement is checked to see if it’s true or not. If it is true, the code block under the “if” statement is run. If the statement is false, all the statements under the “else” statement are run in that place.

  • Loops

Loops are a way of Python coding that allows you to continue a specific task for a given number of iterations while something else is happening. The commands required to build loops are for and while. These loops are vital components of any program; they are used to repeat blocks of code for a certain number of times.

  • Functions

Functions are blocks of reusable code that help to perform a specific task. In Python, a function is declared by “def” before the name of the function. Python doesn’t need to specify the function’s return type. The function can be used by writing the name and the parameter list in the brackets.

  • Modules

In Python, modules allow programmers to write modular, reusable, and even organized code. Creating a module helps define functions or variables once and then reuse them throughout the code by importing the module. This saves time, improves readability, and reduces errors.

Start Building Your Python Skills

As you embrace the idea of making a great career in this enthusiastic and high-demand Python industry, you must build your skills. With the proper guidance and training through the Python course, you can be proficient in the section and enhance your knowledge about variables, data structures, control structures, and file handling.

Until you enrol in the best Python course, let us give you a brief overview of the foundation that will help you build your skills in the sector.

  • Data Structures

Python includes various built-in data structures, such as lists, tuples, sets, and dictionaries. These structures are considered containers that help sort and group data according to type.

  • Lists

Lists are simple containers that are considered an integral part of the Python language. A single list might contain data types like Strings, Integers, and Objects. Python lists are known as the dynamically sized arrays that are declared in other languages (vector in C++ and ArrayList in Java). They are enclosed in [] and separated by commas.

  • Dictionaries

Python dictionaries are similar to the real-world dictionaries. These mutable data structures contain a collection of keys and are associated with values. This structure makes them quite similar to the word-definition dictionaries.

  • Sets

In Python, sets are mutable dynamic collections of immutable elements. The elements contained in a set must be unique, as duplicates are not allowed. Thus, sets can be easily used to remove duplicates from a list.

  • Tuples

Tuples are identical to lists, contain a sorted and ordered collection of elements, and are immutable. They can be used when a data structure cannot be modified anymore. If all the elements are immutable, they can also be used as dictionary keys.

File Handling

File handling enables the storage of data that can be accessed by code for multiple purposes, such as writing, reading, modifying, and deleting data from files. It allows handling a file like an object so that various functions can be performed on the file.

Reading from and writing to files is a common task. You can write a message to a file and then read it back, thus demonstrating how Python handles file operations efficiently.

When a file is opened in reading mode, Python provides different methods like read(), readline(), and readlines() to fulfil various reading requirements. The read() method outputs the whole content at once, whereas readline() reads one line at a time. readlines() focuses on the entire file content as a list of lines.

Writing to a file in Python is just like reading. Open a file in write or append mode and use the write() or write lines () methods. The write() method engraves a string onto the file, and write lines () inscribes a list of strings as a separate line.

Exception Handling

For robust programs, graceful error handling is important. In Python, using try-except blocks, you can manage exceptions like dividing by zero without crashing the program. In the file handling part, errors are enormous obstructions.

Python’s try-except blocks work as the suspension system, absorbing shocks from FileNotFoundError, IOError, and other exceptions. Wrapping the file operations successfully in these blocks ensures proper handling of challenges.

Step-by-Step Python Learning

The Python language has become a basic part of the present digital ecosystem. It is essential to learn Python programming from scratch and acquire the skill. Python is used in various fields and is gaining popularity across all big tech companies like Google, Meta, Amazon, and Netflix.
