Python Data Science Tutorials
You use Python to explore, analyze, and visualize data with pandas, NumPy, SciPy, and Jupyter. Create clear charts with Matplotlib and Seaborn, clean messy datasets, and write tests so analyses are repeatable. Work through practical tasks like feature engineering, time series, and text processing while using virtual environments to keep tooling reliable.

When you are ready to model, apply scikit-learn for classification, regression, clustering, and pipelines. For deep learning, train with Keras, TensorFlow, or PyTorch and track results. Scale workloads with Dask, store data in SQLite, PostgreSQL, and deploy predictions with FastAPI and Docker.

Install pandas with python -m pip install pandas. Read files using pd.read_csv() or pd.read_parquet(), inspect with df.info() and df.describe(), and summarize with groupby() and agg().
Use scikit-learn for classical ML tasks and pipelines. Choose TensorFlow or PyTorch for deep learning, and consider XGBoost for strong tabular baselines.
Start with Matplotlib for full control and Seaborn for quick, statistical plots. Set styles, labels, and legends, and export figures with plt.savefig() for reports and dashboards.
Use Dask for pandas-like processing on larger-than-memory data, or PySpark when you need a cluster. For single-machine workflows, stream with chunksize, downcast dtypes, and store data as Parquet.
Serialize the model with joblib.dump(), load it in a FastAPI app, and expose a POST /predict endpoint. Run with Uvicorn or behind Gunicorn, and containerize with Docker for consistent releases.
