Interpreters VS compilers #īefore we can precisely understand what are Cython and Numba, let’s discuss the basics of compilers and interpreters.Ī common mistake when understanding compilers is to think that the output of the compiler is necessarily machine code - code written in a low-level programming language that is used to directly manipulate the central processing unit (CPU). What are they, what are they good for and why people still use C/C++ with much more complicated syntax? 15.2. In this notebook we are going to discuss tools designed to provide C-like performance to Python code: Cython and Numba. But we have already encountered situations when it was not possible to avoid running Python loops that easily end up being painfully slow. scikit-learn or TensorFlow).Īs we discussed earlier, NumPy and SciPy integrate optimized and precompiled C code into Python and, therefore, might provide a significant speed up. Python also dominates the data-science due to availability of packages such as NumPy, SciPy and versatile machine learning tools (e.g. On the contrary, Python is a great tool for various tasks that do not require running expensive simulations (web-development, scripting). It doesn’t make Python a bad programming language.

There are two major reasons for that: Python is a dynamically typed language and Python is an interpreted language. But Fortran, C, C++ dominate high-performance programming. Python has plenty of appeal to the programming community: it’s simple, interactive and free.
