Print statement in Python

Python libraries for data science and Machine Learning 👇👇

1. NumPy: NumPy is a fundamental package for scientific computing in Python. It provides support for large multidimensional arrays and matrices, along with a collection of mathematical functions to operate on these arrays.

2. Pandas: Pandas is a powerful data manipulation and analysis library that provides data structures like DataFrames and Series, making it easy to work with structured data.

3. Matplotlib: Matplotlib is a plotting library that enables the creation of various types of visualizations, such as line plots, bar charts, histograms, scatter plots, etc., to explore and communicate data effectively.

4. Scikit-learn: Scikit-learn is a machine learning library that offers a wide range of algorithms for classification, regression, clustering, dimensionality reduction, and more. It also provides tools for model selection and evaluation.

5. TensorFlow: TensorFlow is an open-source machine learning framework developed by Google that is widely used for building deep learning models. It provides a comprehensive ecosystem of tools and libraries for developing and deploying machine learning applications.

6. Keras: Keras is a high-level neural networks API that runs on top of TensorFlow, Theano, or Microsoft Cognitive Toolkit. It simplifies the process of building and training deep learning models by providing a user-friendly interface.

7. SciPy: SciPy is a scientific computing library that builds on top of NumPy and provides additional functionality for optimization, integration, interpolation, linear algebra, signal processing, and more.

8. Seaborn: Seaborn is a data visualization library based on Matplotlib that provides a higher-level interface for creating attractive and informative statistical graphics.
