"Python is slow" is a misunderstanding. For instance, if you use some of the most popular libraries (like Numpu, Scipy, Panda, etc.), then is too fast compared to core Python code. It is because of the most libraries are written in best language for the different platform. For instance, most code of... read more
"Python is slow" is a misunderstanding. For instance, if you use some of the most popular libraries (like Numpu, Scipy, Panda, etc.), then is too fast compared to core Python code. It is because of the most libraries are written in best language for the different platform. For instance, most code of Numpy is written in C/C++. In addition, there are many python tools for optimal utilization of the underlying hardware. For instance, Theano/Theanets/Keras takes code in python, and they "convert" your coding in the best way possible for your system. It can use underlying GPU, multiple processors, or cluster without much efforts. Because of this, you don't have to learn C, C++, CUDA, OpenCV, etc. Python is very popular for it's simplistic and readability. Because of simplicity, it's popular in search. A researcher can write modify his/her experiment quickly. Readability is one of the important factors in an industry environment as maintenance of software takes 60-80% of the total effort. In addition to above, what else one needs? Good libraries for various tasks? There are lots of libraries. You name the task, and most likely there will be a library. This makes the development of software and experiment-setup for research very easy. read less

Very good question............ a thing is in use ONLY as long as it has some ADVANTAGE over other. Every language has its own pros & cons. There are situations/applications where speed of execution is of second importance. Python has several advantages , it is a DEVELOPERS delight , because 1.It has simplest syntax 2. it has the best in-built functions , no other language has as many functions on data structures like lists, dictionaries, etc 3. It has best & fastest libraries/frameworks for latest technologies like Data Science, Machine learning, Big data, web development , Scientific & Numerical programming, Embedded systems, IoT etc . read less
