SCIP is a solver for a wide variety of mathematical optimization problems. It is written in C and extendable due to its plug-in based design. However, dealing with all C specifics when extending SCIP can be detrimental to development and testing of new ideas. This paper attempts to provide a remedy by introducing PySCIPOpt, a Python interface to SCIP that enables users to write new SCIP code en...

We introduce MathChem, an open-source and cross-platform Python package, aimed at supporting research in mathematical chemistry. MathChem enables researchers to load batches of molecules or molecular graphs from external files or NCI online database, calculate topological indices, perform statistical analyses and visualize the results. As a Python package, MathChem is easily integrable with Sag...

Programmers may be hesitant to use declarative systems, because of the associated learning curve. In this paper, we present an API that integrates the IDP Knowledge Base system into the Python programming language. IDP is a state-of-the-art logical system, which uses SAT, SMT, Logic Programming and Answer Set Programming technology. Python is currently one of the most widely used (teaching) lan...

In the project, we explore LU decomposition with or without pivoting to compute systems of linear equations which are fundamental to any linear algebra problems. We used modular programming in Fortran to perform LU decomposition, forward and backward substitution for three different systems of linear equations. We used python to execute Fortran and compare results generated from our Fortran pro...

This paper describes MoPy, a port of the Python 1.5.2 interpreter to the Psion 5/Epoc32 platform and Koala, a CORBA-style Object Request and Event Broker implemented natively in Python. While primarily a direct POSIX-based port of the standard Python interpreter, MoPy also adds thread, socket and serial support for the Psion platform. The Koala ORB is designed particularly with MoPy in mind and...

Pentastomes are worm-like endoparasites of the phylum Pentastomida found principally in the respiratory tract of reptiles, birds, and mammals. They cause a zoonotic disease known as pentastomiasis in humans and other mammals. The autopsy of a Nigerian royal python (Python regius) revealed two yellowish-white parasites in the lungs, tissue necrosis and inflammatory lesions. The parasite was conf...

Python programming language has experienced a great progress and growing use in the scientific community in the last years as well as a direct impact on solar physics. Python is a very mature language and almost any fundamental feature you might want to do is already implemented in a library or module. SunPy is a common effort of, using the advantages of Python, developing tools to be applied f...

Even with the increase in the number and variety of computer resources available to research scientists today, it is still challenging to construct scalable distributed applications. To address this issue, we developed Work Queue, a flexible master/worker framework for building large scale scientific ensemble applications that span many machines including clusters, grids, and clouds. In this pa...

The Python programming language has a number of advantages, such as simple and clear syntax, concise and readable code, and open source implementation with a lot of extensions available, that makes it a great tool for teaching programming to students. Unfortunately, Python, as a very high level interpreted programming language, is relatively slow, which becomes a nuisance when executing computa...
