Why Not Python?

Why Not Python?

While Python is an excellent environment for building computationally-intensive scientific applications and building most kinds of general-purpose systems, there are a number of uses for which Python may be less suitable. As Python is an interpreted programming language, in general, most Python code will run substantially slower than code written in a compiled language like Java or C++. As programmer time is typically more valuable than CPU time, many are happy to make this tradeoff. However, in an application with very low latency requirements (for example, a high-frequency trading system), the time spent programming in a lower-level, lower-productivity language like C++ to achieve the maximum possible performance might be time well spent. Python is not an ideal language for highly concurrent, multithreaded applications, particularly applications with many CPU-bound threads. The reason for this is that it has what is known as the global interpreter lock (GIL), a mechanism that prevents the interpreter from executing more than one Python bytecode instruction at a time. The technical reasons for why the GIL exists are beyond the scope of this book, but as of this writing, it does not seem likely that the GIL will disappear anytime soon. While it is true that in many big data processing applications, a cluster of computers may be required to process a data set in a reasonable amount of time, there are still situations where a single-process, multithreaded system is desirable. This is not to say that Python cannot execute truly multithreaded, parallel code; that code just cannot be executed in a single Python process. As an example, the Cython project features easy integration with OpenMP, a C framework for parallel computing, in order to parallelize loops and thus significantly speed up numerical algorithms.

WHAT ARE NEURAL NETWORKS? | Comingfly

WHAT ARE NEURAL NETWORKS ? Neural Networks the process of machine learning are neural networks. These are brain-inspired networks of interconnected layers of algorithms, called neurons, that feed data into each other, and which can be trained to carry out specific tasks by modifying the importance attributed to input data as it passes between the layers. During training of these neural networks, the weights attached to different inputs will continue to be varied until the output from the neural network is very close to what is desired, at which point the network will have 'learned' how to carry out a particular task. A subset of machine learning is deep learning, where neural networks are expanded into sprawling networks with a huge number of layers that are trained using massive amounts of data. It is these deep neural networks that have fueled the current leap forward in the ability of computers to carry out task like speech recognition and computer vision. T he

** How to Always Choose Happiness. 1. Determine What Happiness Means to You “The greatest discovery of any generation is that a human can alter his life by altering his attitude.” 2. Understand How Happiness Works for You “Happiness is not a feeling it’s an action. In order to feel happy you have to do happy.” 3. Choose to Be Around the Right People “The people you surround yourself with influence your behaviors, so choose friends who have healthy habits.” 4. Commit to Helping Others “The purpose of life is not to be happy. It is to be useful, to be honorable, to be compassionate, to have it make some difference that you have lived and lived well.” 5. Choose to Take Care of You – Mind Body and Spirit “Self-care is a deliberate choice to gift yourself with people, places, things, events, and opportunities that recharge our personal battery and promote whole health—body, mind, and spirit.”

why we use Numpy in python

why we use NumPy in python NumPy is a general-purpose array-processing package. It provides a high-performance multidimensional array object and tools for working with these arrays. It is the fundamental package for scientific computing with Python . A powerful N-dimensional array object. Syntex:- import numpy arr = numpy.array([ 1 , 2 , 3 , 4 , 5 ]) print (arr) Output:- [1 2 3 4 5] NumPy is a basic level external library in Python used for complex mathematical operations. NumPy overcomes slower executions with the use of multi-dimensional array objects. It has built-in functions for manipulating arrays. We can convert different algorithms to can into functions for applying on arrays. NumPy arrays are faster and more compact than Python lists. An array consumes less memory and is convenient to use . NumPy uses much less memory to store data and it provides a mechanism of specifying the data types.
