Visit python.org/downloads.
Download the latest version (e.g., Python 3.11 as of June 2025).
Tip: Check “Add Python to PATH” during installation on Windows.
Install Python:
Run the installer and follow prompts.
On macOS/Linux, use the terminal to verify: python3 --version.
Example: Output should show “Python 3.11.x”.
Install Libraries:
Open a terminal (Command Prompt on Windows, Terminal on macOS/Linux).
Install pandas and scikit-learn:
bash
pip install pandas scikit-learn
Tip: U.S. learners can access fast download speeds via pip’s servers.
Verify Installation:
Open a Python shell (type python3 in terminal).
Test:
python
import pandas
print("pandas installed successfully!")
If no errors, you’re ready to code locally.
Step 3: Using Python in Google Colab
Import Libraries: Start your Colab notebook with:
python
import pandas as pd
import sklearn
Upload Datasets:
Click the folder icon in Colab’s left sidebar.
Upload a U.S. dataset (e.g., retail CSV from Kaggle).
Load with:
python
data = pd.read_csv('retail_data.csv')
Run Code: Use the play button to execute code cells.
Step 4: Troubleshooting
Colab Issues: Ensure a stable internet connection, common in U.S. urban areas. Restart the runtime if errors occur (Runtime > Restart).
Python Issues: Update pip (pip install --upgrade pip) for library installation problems.
Support: Contact asktenali.com or join U.S. AI communities (e.g., Data Science USA) for help.
Step 5: Recommended Setup for U.S. Learners
Browser: Use Chrome or Firefox for optimal Colab performance.
Hardware: Any modern laptop (e.g., widely available in U.S. stores like Best Buy) with 4GB RAM is sufficient for Colab.
Internet: U.S. broadband (e.g., Comcast, Verizon) ensures smooth Colab access.
