Setting up Python Development Environmen

We will be utilizing Replit (www.replit.com), a complete and free online platform that facilitates the development and execution of programs directly through your web browser. It features a sophisticated text editor with syntax highlighting, making it an ideal environment for Python programming.

Replit’s versatility allows it to be used across various devices and operating systems, including iPads, iPhones, Android devices, ChromeBooks, and even Windows 10 Home S, making it suitable for environments where software installations are restricted.

To begin your first Python project on Replit, after signing in, head over to the ‘Files’ section and initiate a new document titled main.py. Following this, input the line: print(‘Hello world’)

After saving and executing the file, you will observe the output “Hello world”.

Modifying the message to ‘Hello Cyber world’ and executing again will display your updated program.

Although initially unfamiliar, acquiring basic Linux skills is beneficial, as it underpins most server systems.

For more complex scripts, transitioning to using a Linux shell (command line) becomes necessary. Switching to the shell view reveals the Linux command prompt. From here, executing your ‘main.py’ script involves a series of commands to navigate directories and manage files. Commands such as ‘cd’ to change directories, ‘pwd’ to display the current directory, and ‘ls -l’ to list files in detail are fundamental. Executing ‘python3 main.py’ runs your script.

Editing Files in Replit Replit offers multiple methods for file editing, from straightforward to advanced. Files can be edited directly from the main file panel, or via the command line using editors like nano or vim. Each editor has its own set of commands for saving and exiting files, with vim requiring a bit more practice to navigate efficiently.

Becoming adept with the bash console and its shortcuts, such as utilizing the arrow keys to revisit past commands, boosts productivity. Clearing commands helps in keeping a neat workspace. For additional insights on commands, check out my Linux series.
