    Python is one of the trending programming languages with rapid growth in Artificial Intelligence, and Machine learning python has gained too much popularity in the past few years. Python's popularity is not only because it is used in Machine learning or data science, but it also has an insane number of libraries which opens the use of Python for any development.

    With Python, we can do web development, scripting, game development, Data Science stuff, and so many extra things. Its simple syntax helps developers to implement complex algorithms with ease.

    Here in this article, we have mentioned the top 10 Python libraries which are heating the developer community and trending topics like AI, ML, Data Science, and lots more.

    What is a Library?

    A library is a collection of pre-written code that you can import into your code to add some extra functionality. We use libraries, so we do not have to write code from scratch. Instead, we use a library so we can use the pre-written code, functions, or classes and use its functionality to enhance our code.

    Python has many libraries, and for different development, we have different libraries in Python. All the libraries we have provided here belong to the Python 3 version because Python 2 is no longer in use.

If you are an intermediate python developer, you must have heard of this Library because this Library provides one of the most basic Data Structures that every high-level programming language should have. Python does not have a built-in array Data Structure though it has a Data Structure called list, which looks similar to an array but does not perform all the operations that an array is supposed to do. Apart from the array, it also provides many mathematical functionalities like a matrix (which is also a part of the array).

    NumPy Features:

    • This Library has good documentation
    • Provides many mathematical functionalities to Python
    • It is straightforward to learn
    • Play a very vital role in Data Science

This Python library is commonly used for Data Science using Python; it is also an open-source library with tremendous community support. It is a collection of many mathematical algorithms, but it is specifically used to solve statistics problems. Many other libraries are used for data science, but SciPy is the simplest.

    SciPy Features

    • Large community support
    • Rapid development
    • Simple data science tool
    • Easy to get started

    5. Keras

    It is an open-source and High-level neural Network python library commonly used for deep learning algorithms and experiments. This library is written in Python itself, making it capable of running on top of other Machine learning libraries used by Python. Keras also use Theano and TensorFlow at the backend to perform many tasks. The main drawback of Keras is its speed compared to other machine learning libraries; slowly, developers do not consider this Library for their projects.

    Keras Features:

    • Keras has many features like compiling models, processing data-sets, visualization of graphs, etc.
    • It provides a modular approach to our models.
    • It is entirely based on Python that's why it is easy to debug
