Python is a multi-paradigm programming language. Object-oriented programming and structured programming are fully supported, and many of their features support functional programming and aspect-oriented programming (including metaprogramming [ 70] and metaobjects ). [ 71] Many other paradigms are supported via extensions, including design by ...
For example, in Python, to print the string Hello, World! followed by a newline, one only needs to write print ("Hello, World!" In contrast, the equivalent code in C++ [ 7 ] requires the import of the input/output (I/O) software library , the manual declaration of an entry point , and the explicit instruction that the output string should be ...
Mojo is a programming language in the Python family that is currently under development. [ 3][ 4][ 5] It is available both in browsers via Jupyter notebooks, [ 5][ 6] and locally on Linux and macOS. [ 7][ 8] Mojo aims to combine the usability of higher level programming languages, specifically Python, with the performance of lower level ...
Parse tree of Python code with inset tokenization Syntax highlighting is often used to aid programmers in recognizing elements of source code. The language above is Python. A programming language's surface form is known as its syntax. Most programming languages are purely textual; they use sequences of text including words, numbers, and ...
In object-oriented programming languages such as Java, reflection allows inspection of classes, interfaces, fields and methods at runtime without knowing the names of the interfaces, fields, methods at compile time. It also allows instantiation of new objects and invocation of methods. Reflection is often used as part of software testing, such ...
OpenCL (extension of C and C++ to use the GPU and parallel extensions of the CPU) OptimJ (extension of Java with language support for writing optimization models and powerful abstractions for bulk data processing) Perl. Pike. PowerShell. Python (embedded in Maya, Blender, and other 3-D animation packages) Rexx.
Structured programming. Structured programming is a programming paradigm aimed at improving the clarity, quality, and development time of a computer program by making extensive use of the structured control flow constructs of selection ( if/then/else) and repetition ( while and for ), block structures, and subroutines .
Observer pattern. In software design and engineering, the observer pattern is a software design pattern in which an object, named the subject, maintains a list of its dependents, called observers, and notifies them automatically of any state changes, usually by calling one of their methods . It is often used for implementing distributed event ...
