You can use the help function for each numerical method to find out more about the source of the implementation. As a rule of thumb, we expect compiled code to be two orders of magnitude faster than pure Python code. They will thus execute much faster than pure Python code (which is interpreted). Many of the numerical algorithms available through scipy and numpy are provided by established compiled libraries which are often written in Fortran or C. Scipy package (SCIentific PYthon) which provides a multitude of numerical algorithms and which is introduced in this chapter. The matplotlib package (also knows as pylab) provides plotting and visualisation capabilities (see 15-visualising-data.ipynb) and the The numpy module provides a data type specialised for “number crunching” of vectors and matrices (this is the array type provided by “ numpy” as introduced in 14-numpy.ipynb), and linear algebra tools. We list three such modules in particular: Provide numerical tools for frequently occurring tasksĪnd are more efficient in terms of CPU time and memory requirements than using the code Python functionality alone. However, there are dedicated (third-party) Python libraries that provide extended functionality which The core Python language (including the standard libraries) provide enough functionality to carry out computational research tasks.
