In the previous post, we learnt about IDEs and Code editors. In this post, we will learn how to setup Replit for writing code in python.

Repltit Introduction

Replit is free online coding workspace that we can use to get started with python with minimal setup.

Key features

• Online IDE: Replit provides an integrated development environment (IDE) that runs directly in our web browser. You don’t need to install anything locally; just visit the Replit website and start coding.

• Python Support: Replit fully supports Python. We can create Python projects, write Python code, and execute it instantly. It’s a great way to practice Python concepts without worrying about setup.

• Code Editor: Within Replit, there’s a code editor where we write your Python programs. It offers features like syntax highlighting, autocompletion, and error checking.

• Collaboration: Replit allows real-time collaboration. You can invite friends or classmates to work on the same project simultaneously. It’s like Google Docs for coding!

• Project Management: We can organize our Python projects using Replit’s workspace. Create folders, manage files, and keep everything tidy.

• Run Code: Click the “Run” button, and the Python code executes instantly. You’ll see the output right there in the same window.

• Learn by Doing: Replit encourages hands-on learning. Try out Python examples, experiment with code, and see immediate results.

Python with Replit

Remember our first python code we wrote? Well, let’s see how we cab rewrite it in replit.

• Step 1: Go to the replit website and sign up for an account.

  

  

• Step 2: Create a repl. Select python from the list of templates and Name your file. Then click “Create Repl”

  

• Step 3: Now we can write our program we wrote earlier(print(“Hello world”)) and click run.

  

Conclusion

There you go! We have rewritten our helo world pyhon program in replit. Now you can code in any bowser or download the replit app and continue coding anytime.

In the previous post we installed python and wrote our first Python program using Windows Notepad. Now notepad is a good editor if you want to quickly edit something or write a small and simple program but for more complex programs we use an IDE or a code editor as it gives us more features to make things easier.

Code Editors

Code editor is a specialized text editor designed specifically for writing and editing code. It provides features that simplify the process of coding, making it easier and more efficient for programmers and developers. VS code, Sublime Text, Atom, are some examples of Code edittors.

Key Features

• Syntax Highlighting: Code editors highlight keywords, operators, and other elements of a programming language in different colors to make the code more readable and easier to understand.

• Autocomplete: This feature suggests completions for partially typed words or code structures, which can speed up coding and reduce errors.

• Code Formatting: Code editors often include tools to automatically format your code according to standard style guidelines, ensuring consistent and readable code.

• Error Detection: Many code editors can detect syntax errors and other common coding mistakes in real-time, helping developers correct issues before running their code.

• Extensions and Plugins: Code editors typically support various extensions and plugins that add functionality, such as debugging tools, version control integration, and language-specific features.

• Multiple Language Support: Good code editors support a wide range of programming languages, allowing developers to work on different types of projects within the same environment.

Integrated Development Environment(IDE)

An Integrated Development Environment(IDE) is a software that provides a complete set of tools for software development. Unlike a simple code editor, an IDE integrates various development tools into a single interface, offering a more cohesive and efficient workflow for developers. Some examples include, Pycharm(IDE for python), IntelliJ IDEA(IDE for java), Xcode(IDE for making apple apps), etc.

Key Features

• Code Editor: At the core of an IDE is a code editor that often includes advanced features like syntax highlighting, code completion, and code folding.

• Compiler/Interpreter: IDEs often include compilers or interpreters for the languages they support, allowing developers to compile or interpret code directly within the environment.

• Debugger: Integrated debugging tools help developers find and fix errors in their code by allowing them to step through code execution, set breakpoints, inspect variables, and analyze the call stack.

• Build Automation Tools: IDEs usually include build automation tools that streamline the process of compiling, linking, and packaging code into executable programs or libraries.

• Version Control Integration: Many IDEs integrate with version control systems like Git, enabling developers to manage code repositories, track changes, and collaborate with others without leaving the environment.

• Project Management Tools: IDEs often provide tools for managing project files and directories, configuring project settings, and handling dependencies.

• Code Navigation and Refactoring: Features like go-to-definition, find references, and automated refactoring make it easier to navigate and improve code.

• Testing and Profiling Tools: Some IDEs include tools for running unit tests and profiling code performance, helping developers ensure their code is correct and efficient.

• Integrated Terminal: An integrated terminal or command-line interface allows developers to execute commands and scripts directly within the IDE.

• Plugin and Extension Support: Many IDEs support plugins and extensions that add additional functionality, such as support for new languages, frameworks, and tools.

IDE vs Code Editor

There might be a confusion on which one to use so here is a comparison table for an IDE vs a Code Editor.

Hello everyone! In this guide we’ll be seeing how to setup python on your computer.

Downloading and Installing the Python Interpreter

1. Downloading: Go to the www.python.org/downloads and download the latest version of python.

2. Installing: Once you download the installer. Open it and install according to the instructions given in the installer. Also don’t forget to check the “Add python.exe to PATH” checkbox. It add python to path so that we don’t have to go to it’s installed folder to run it everytime.

Compilers/Interpreters

Computers understand only one language and that’s binary(0101001), but since we’ll be giving instructions(programming) in python, we need something to convert our program to computer understandable code(also called machine code).

This is where compilers/interpreters come in, these are software whch convert our code(source code) to machine code. When we installed python we actually installed the interpreter with some aditional tools. For more information on Compilers and interpreters see the explanation from geeksforgeeks.

Python is a interpreted language, meaning it uses and interpreter and that’s exactly what we installed(well with some aditional tools).

Writing Our First Python Program

Now that we have installed an interpreter, we can write and run code with it:

1. Open Notepad(or you can use any text editor u like). and type:

   print("Hello World")
   

   

2. Save the file as hello.py on your Desktop(You can use any one word name for now).

3. Open Command Prompt and type:

   cd Desktop
   python hello.py
   

4. Output

Conclusion

Congratulations for running your first python program. In the next blog, we’ll see what code editors are and how we use them. Thanks for reading.
