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.
