“Big things have small beginnings.” ~ Promethus

Hey there, Python learner..

Setting up a virtual environment (or venv) is an essential part of any Python project.

It helps keep dependencies organized and avoids conflicts with other projects.

Here’s a quick and friendly guide on:

how to create a virtual environment.
verify it
even check where your packages are being installed._

Step 1: Create the Virtual Environment

To kick things off, open your terminal or command prompt and run this command:

python -m venv venv

You should see a folder named venv—that’s your virtual environment! 🎉

ls

Step 2: Activate the Virtual Environment⚡

source venv/Scripts/activate

After running this command, your prompt will change to something like below image:👇

Step 3: Verify the Active Environment🔍

which python

Step 4: Install a Package and Verify Installation📦

Try installing any package, here i am installing boto3 which is an official AWS SDK for python.

pip install boto3

This will show all the packages installed in your virtual environment, including boto3

pip list

Step 5: Deactivate the Virtual Environment🔒

Once deactivated, run pip list again, it will show the packages installed globally, rather than the ones in your virtual environment.

deactivate venv

pip list

And that’s it!🎊

You’re set to use virtual environments in Python.

So go ahead—give it a try!

Always remember: Experiment, break things, fix them, and watch your projects run smoothly.🚀

Master -> Main branch in 2024

Hey there!

As we all know, in October 2020 git community made a meaningful change by deciding to shift the default branch name from "master" to "main."

Personally, I didn't have any problem using "master" as the default branch name. However, as we keep upgrading ourselves in tech, it was inevitable to accept this change and rename our "master" branch to "main," incorporating the "main" branch in our new repositories.

Today, I was checking an old repository that I created back in 2019, and it was mostly empty. I decided to repurpose that same repository for my new projects, so I chose to change the "master" branch to "main" since I’m used to it now.

Now we'll look into simple steps to rename "master" -> "main"

Using the GitHub Interface:

Head over to your repository.
Click on Settings -> General -> Default branch.
Hit Edit and change the branch name to "main."

In this screenshot, I’ve already made the change, but yours should look pretty similar!

Updating Your Local Clone

If you’ve got a local clone of the repo, don’t worry—you can easily update it too! Just run these commands in your terminal:

git branch -m master main
git fetch origin
git branch -u origin/main main
git remote set-head origin -a

Thanks for reading my article :)

Happy coding, and don’t hesitate to share your thoughts.
