Applications of Python

  • Web Applications: Python may be used to develop a wide variety of online applications and content management systems. Flask, Plone, Django, and Pyramid are a few suggested frameworks for building online applications.
  • Scientific and Numeric Computing: Python abounds with libraries for scientific and numeric computing. Libraries like SciPy and NumPy can be used for general computation. You can use EarthPy for Earth science. You have AstroPy for astrology and so on.
  • Creating Software Prototypes: Prototyping is frequently done in Python. Your game's prototype may be made with Pygame.

Python vs. C++ for AI

  • Python is more famous than C++ in the developer community. The reason behind this is that Python is easy to learn and implement.
  • Performance-wise C++ is better than Python. The reason behind this is that C++ is a statically typed language. Hence, typing errors are minimal in this case. Moreover, C++ creates faster programs.
  • Python can be used to implement functionality even with less code. Python is dynamic while C++ is platform-specific.
  • The development of the GPU has given Python an edge over C++.

Top Python Libraries

Top python libraries

1. TensorFlow

To carry out difficult numerical computations, TensorFlow is employed. It is capable of partial differential equation (PDE), word embedding, deep learning, neural networks, image recognition, handwritten digit classification, and natural language processing (NLP).

Abstraction is the major advantage of utilising TensorFlow. This enables programmers to concentrate on logic and leave the computer to handle the specifics of algorithm implementation. You may use it to make one-of-a-kind, responsive apps that you can use on desktop, Android, or iOS platforms.

Advantages of TensorFlow:

  • TensorFlow provides better graph visualization techniques.
  • TensorFlow is backed by Google. You can get regular updates and new features.
  • TensorFlow can be used in a wide variety of platforms like Windows, Linux, macOS and even smartphones.

2. Keras

An open-source library called Keras is used to build machine learning applications like neural networks. It is compatible with MXNet, Deeplearning4j, TensorFlow, Theano, and Microsoft Cognitive Toolkit (CNTK). It includes nearly all required components, such as neural layers, optimizers, initialization plans, functions for activation, cost functions, and regularisation strategies.

With Keras, adding new modules is a breeze. The process is analogous to adding new classes and functions. There is no requirement for separate model configuration files because the model is described in the code.

Due of its simplicity of usage, newcomers typically like Keras. Even convolutional neural networks may be handled by it. Modularity and expressiveness are improved with Keras. It has algorithms for the layers of normalisation, activation, and optimizer.

Advantages of Keras:

  • The developer’s experience is given priority in Keras.
  • Keras is widely used in the industry and research community.
  • Keras makes it easy to turn your model into products.
  • Keras supports multiple backends. You can choose any one backend as per your requirement.

3. Theano

  • Theano was developed in the year 2007 and since then it has always been a must-know library in the AI community.
  • Theano allows you to deal with a multidimensional array. It is extensively used in scientific and complex mathematical calculations.
  • With Theano you can perform data-intensive calculations a hundred times faster than your CPU alone. Moreover, it is optimized for GPU as well. In simple terms, the developers have tried their best to make Theano a go-to option when dealing with large calculations regularly.
  • Theano has proved to be a great neural network library because of its fast computations. It can be used to boost the computation time and development time of AI apps. However, it has a disadvantage of being quite hard for beginners.

Advantages of Theano:

  • Theano can be used to stabilize unstable models.
  • In Theano you can optimize the speed by moving from CPU to GPU.
  • Theano can automatically create your symbolic graphs to make data visualization easy.

4. Scikit-learn

Another essential Python package is called Scikit-learn. It has a wide variety of methods for classification, grouping, and regression. Examples include gradient boosting, DBSCAN, random forest, k-means, and vector machines. It is compatible with SciPy and NumPy, two additional Python libraries.

This well-known AI library is available for purchase.
