Task: Setting up VS Code for Python

Objective

Set up and test your Python development environment in VS Code using a virtual environment.

Open your terminal and verify that Python is installed: bash python3 --version

Open VS Code and install the following: • Python extension • Jupyter extension

In the terminal (inside your project folder), run:

python3 -m venv .venv
source .venv/bin/activate       # macOS/Linux

.\.venv\Scripts\Activate.ps1    # Windows

Then install a few essential packages:

pip install jupyter numpy scikit-learn matplotlib pandas

Launch Python from within your activated environment and check:

import numpy as np
print(np.__version__)

•   Create a new file called test.py
•   Add the following code:

import numpy as np
print("NumPy works!", np.__version__)

•   Create a new notebook named test.ipynb
•   In the first cell, add:

import numpy as np
np.random.rand(3)

• Run the cell and confirm it executes successfully.

Upload your test.ipynb to Google Colab. In the first cell, install NumPy and run:

!pip install numpy
import numpy as np
print("NumPy works in Colab!", np.__version__)
