Python is a popular programming language that uses reference counting to manage heap objects. Python also has a Foreign Function Interface (FFI) that allows Python extension modules to be written in native code such as C and C++. Native code, however, is outside Python’s system of memory management; therefore extension programmers are responsible for making sure these objects are reference coun...

Version 2.5 of the Python programming language contains no mechanism for restricting access to resources by Python code. This is a slight hindrance to the language as it is used in many situations, such as a domain-specific language in other applications, where some mechanism to control what resources Python code can access would be helpful. Python did once have a security mechanism for restric...

BACKGROUND Nineteen clinically normal snakes: six ball pythons (Python regius), six Burmese pythons (Python bivittatus), one Children's python (Antaresia childreni), four Amazon tree boas (Corallus hortulanus), and two Malagasy ground boas (Acrantophis madagascariensis) were subjected to ultrasound imaging with 21 MHz (ball python) and 50 MHz (ball python, Burmese python, Children's python, Ama...

Introduction: Internal radiation dosimetry is important from a radiation protection point of view and can help to optimize the radiation dose delivered to the workers, public, and patients. It has a rather simple protocol but needs a large amount of data. Therefore, it is difficult to do on a routine basis. The use of computer programs makes internal radiation dosimetry simpler...

VTK and ParaView are leading software packages for data analysis and visualization. Since their early years, Python has played an important role in each package. In many use cases, VTK and ParaView serve as modules used by Python applications. In other use cases, Python modules are used to generate visualization components within VTK. In this paper, we provide an overview of Python integration ...

This technical note introduces the Python bindings for libcloudph++. The libcloudph++ is a C++ library of algorithms for representing atmospheric cloud microphysics in numerical models. The bindings expose the complete functionality of the library to the Python users. The bindings are implemented using the Boost.Python C++ library and use NumPy arrays. This note includes listings with Python sc...

We introduce an MPI Python module, MYMPI, for parallel programming in Python using the Message Passing Interface (MPI). This is a true Python module which runs with a standard Python interpreter. In this paper we discuss the motivation for creating the MYMPI module, along with differences between MYMPI and pyMPI, another MPI Python interpreter. Additionally, we discuss three projects that have ...

Our experiences interfacing Python with optimization software are presented. The same work was done using extension programming and scripting. Due to the nature of the C libraries we were using, we found problems related to memory corruption and C namespace collisions when we used the libraries as Python extensions. For our application and the software we are interfacing to, we found that using...

The Python programming language is becoming increasingly popular in a variety of areas, most notably among novice programmers. This paper presents an implementation of Python for DrRacket which allows Python programmers to use DrRacket’s features with Python code, as well as adding Python support for DrRacket based tools, such as Rosetta. The suggested approach involves compiling Python code in...

Magnetoencephalography and electroencephalography (M/EEG) measure the weak electromagnetic signals generated by neuronal activity in the brain. Using these signals to characterize and locate neural activation in the brain is a challenge that requires expertise in physics, signal processing, statistics, and numerical methods. As part of the MNE software suite, MNE-Python is an open-source softwa...
