This paper focuses on the role of python in dramatic increase in productivity and high-level of code reuse in computational science. The salient features of python make it an ideal language for scientific computing exposing the shortcomings of legacy languages and prototyping platforms. Python provides a rich collection of built-in data types such as strings, lists, dictionaries; dynamic typing...

Racket is a descendent of Scheme that is widely used as a first language for teaching computer science. To this end, Racket provides DrRacket, a simple but pedagogic IDE. On the other hand, Python is becoming increasingly popular in a variety of areas, most notably among novice programmers. This paper presents an implementation of Python for Racket which allows programmers to use DrRacket with ...

The cardiovascular actions of python bradykinin (BK) and substance P (SP) have been investigated in the anesthetized ball python, Python regius. Bolus intra-arterial injections of python BK (0.03-3 nmol/kg) produced concentration-dependent increases in arterial blood pressure, heart rate (HR), and cardiac output concomitant with small decreases in systemic resistance and stroke volume. Intra-ar...

The Python library FatGHol [FatGHoL] used in [Murri2012] to reckon the rational homology of the moduli space of Riemann surfaces is an example of a non-numeric scientific code: most of the processing it does is generating graphs (represented by complex Python objects) and computing their isomorphisms (a triple of Python lists; again a nested data structure). These operations are repeated many t...

Object-Z is an object-oriented specification language which extends the Z language with classes, objects, inheritance and polymorphism that can be used to represent the specification of a complex system as collections of objects. There are a number of existing works that mapped Object-Z to C++ and Java programming languages. Since Python and Object-Z share many similarities, both are object-ori...

The Python programming language is becoming increasingly popular in a variety of areas, most notably among novice programmers, due to its readable syntax and extensive libraries. On the other hand, the Racket language and its DrRacket IDE have a tradition for being used to introduce Computer Science concepts to students. Besides, the Racket platform can be extended to support other programming ...

This paper introduces an open source Python toolkit for the Transkribus platform. One part of the toolkit offers a Python client for the Transkribus RESTful interface. The second part offers various Document Understanding tools. The open-source toolkit is freely available through GitHub. Keywords—Transkribus platform, RESTful client, Document Understanding, Conditional Random Fields, Sequential...

NEST is a simulator for large-scale networks of spiking point neuron models (Gewaltig and Diesmann, 2007). Originally, simulations were controlled via the Simulation Language Interpreter (SLI), a built-in scripting facility implementing a language derived from PostScript (Adobe Systems, Inc., 1999). The introduction of PyNEST (Eppler et al., 2008), the Python interface for NEST, enabled users t...

Résumé. Cet article présente une bibliothèque python appelée KNG permettant d’écrire facilement des automates et transducteurs finis. Grâce à une gestion soigneuse des codages et des entrées-sorties, cette bibliothèque permet de réaliser une cascade de transducteurs au moyen de tubes unix reliant des scripts python. Abstract. This paper presents a Python library called KNG which provides facili...
