Compile Windows programs on Linux. This past year I purchased a laptop that came with two drives, a small 24GB SSD and a larger 1TB HDD.
My configuration has placed the root filesystem (i.e. /) on the SSD and my home directory (i.e. /home) on the HDD so that I benefit from very fast system booting and application loading but still have loads of space for my personal files. The only downside to this configuration is that linux is sometimes not the best at ensuring your SSD lives a long life. Unlike HDDs, SSDs have a finite number of write operations before they are guaranteed to fail (although you could argue HDDs aren’t all that great either…). Matplotlib: python plotting. Pyplot. X : array_like, shape (n, m) or (n, m, 3) or (n, m, 4) Display the image in X to current axes.
X may be a float array, a uint8 array or a PIL image. Numpy.array — NumPy v2.0.dev-0c1c499 Manual. Object : array_like An array, any object exposing the array interface, an object whose __array__ method returns an array, or any (nested) sequence. dtype : data-type, optional The desired data-type for the array.
Graphics with Matplotlib. Matplotlib is a large and sophisticated graphics package for Python written in object oriented style.
However, a layer built on top of this basic structure called pyplot accesses the underlying package using function calls. We describe a simple but useful subset of pyplot here. 4.1 Line plots. Python Programming Language – Official Website. Root Finding Method « Numerical Analysis. A root finding algorithm is a numerical method of finding an for a given function such that .
ParallelProcessing. A number of Python-related libraries exist for the programming of solutions either employing multiple CPUs or multicore CPUs in a symmetric multiprocessing (SMP) or shared memory environment, or potentially huge numbers of computers in a cluster or grid environment.
This page seeks to provide references to the different libraries and solutions available. Symmetric Multiprocessing. 17.6. multiprocessing — Process-based “threading” interface — Python v2.6.4 documentation. New in version 2.6. 17.6.1.
Introduction multiprocessing is a package that supports spawning processes using an API similar to the threading module. The multiprocessing package offers both local and remote concurrency, effectively side-stepping the Global Interpreter Lock by using subprocesses instead of threads. Parallel Python - Parallel Python documentation. Module API Quick start guide, SMP Quick start guide, clusters Quick start guide, clusters with auto-discovery Advanced guide, clusters Command line arguments, ppserver.py Security and secret key ppserver.py stats and PID file example PP FAQ 1) Import pp module: import pp 2) Start pp execution server with the number of workers set to the number of processors in the system.
MPI for Python. MPI for Python — MPI for Python v1.2.2 documentation. Mpiexample. Python Tutorial. Python is a general-purpose interpreted, interactive, object-oriented and high-level programming language.
Python was created by Guido van Rossum in the late eighties and early nineties. Like Perl, Python source code is also now available under the GNU General Public License (GPL). This tutorial has been designed for software programmers with a need to understand the Python programming language starting from scratch. This tutorial will give you enough understanding on Python programming language from where you can take yourself to a higher level of expertise. The Python Tutorial — Python v2.7.2 documentation.
Python is an easy to learn, powerful programming language.
It has efficient high-level data structures and a simple but effective approach to object-oriented programming. Python’s elegant syntax and dynamic typing, together with its interpreted nature, make it an ideal language for scripting and rapid application development in many areas on most platforms. Coding style - What is a clean, pythonic way to have multiple constructors in Python. Python - Object Oriented.
Python has been an object-oriented language from day one. Because of this, creating and using classes and objects are downright easy. This chapter helps you become an expert in using Python's object-oriented programming support. If you don't have any previous experience with object-oriented (OO) programming, you may want to consult an introductory course on it or at least a tutorial of some sort so that you have a grasp of the basic concepts. Kapitel 12: Klassen und Objekte. Die Programmiersprache Python. The GNU C Programming Tutorial. Node:Programming with pipes, Next:Low-level file routines, Previous:Single-character input and output, Up:Input and output Programming with pipes There may be times when you will wish to manipulate other programs on a GNU system from within your C program.
One good way to do so is the facility called a pipe . Fgets. Function char * fgets ( char * str, int num, FILE * stream ); Get string from stream Reads characters from stream and stores them as a C string into str until (num-1) characters have been read or either a newline or the end-of-file is reached, whichever happens first. A newline character makes fgets stop reading, but it is considered a valid character by the function and included in the string copied to str. A terminating null character is automatically appended after the characters copied to str. C von A bis Z – 13 Kommandozeilenargumente.
Popen Tutorial. This article will outline how to call shell commands from your C program using the system() call and the popen() functions. The system() call and the popen() call each have their place and differ enough to give an example and explanation of both. Execute a Shell Command Using system() The system() function takes a string as its argument, this string should consist of the shell command you wish to call. Its return value must be run through another function call to retrieve the result of your executed shell command. Cplusplus.com - The C++ Resources Network.
