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. Its simple syntax helps developers to implement complex algorithms with ease. Python 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 type of development, with python we can do web development, scripting, game development, Data Science stuff, and so many extra things. Here in this article, we have mentioned the top 10 Python libraries which are heating up the developer community and trending topic likes AI, ML, Data Science and lots more.

What is a Library?

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

Vamware

Python has a large number of libraries and for different development, we have different libraries in python. Here all the libraries we have provided here belongs to the Python 3 version because Python 2 is not in use anymore.

Top 10 Python Libraries:

  • TensorFlow
  • Pandas
  • Scipy
  • Matplotlib

NumPy

NumPy

NumPy is also one of the most famous python libraries if you are a python intermediate 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 built-in array Data Structure though it has Data Structure called list which looks similar to an array but, it does not perform all the operations that an array supposed to do. Apart from the array it also provides many mathematical functionalities like matrix (which is also a part of the array).

NumPy Features:

  • This library has good documentation
  • Provides many mathematical functionalities to python
  • It is very easy to learn
  • Play a very vital role in Data Science 

SciPy

SciPy

SciPy is similar to NumPy with some distinction, though NumPy and SciPy both support many common features yet we use SciPy when we deal with a large number of data and stats.

SciPy commonly uses for data science using Python, it is also an open source-library with huge community support. Basically, it is a collection of many mathematical algorithms but it is specifically used to solve statistics problem. There are many other libraries which are used for data science but SciPy is the simplest amongst them.

SciPy Features:

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

Keras

Keras

It is an open source and High-level neural Network python library that commonly used for Deep learning algorithms and experiments. This library is written in Python itself which make it capable of running on the top of other Machine learning libraries used by python. Keras also use Theano and TenserFlow at the backend to perform many tasks. The main drawback of Keras is its speed as compared to other machine learning libraries it is quite slow that why developers do not consider this library for their projects.

Keras Features:

  • It has many features like compiling models, processing data-sets, visualization of graphs, and much more.
  • It provides a modular approach to our models
  • It is completely based on python that’s why it is easy to debug
