What can python programming language be used for
Retrieved 13 March Python is often used as a support language for software developers, for build control and management, testing, and in many other ways.
Felix I'm guess he misspoke. Common we all have those moments where we have words or phrases in our heads that make sense while they stay in there - but as soon as they come out of our mouths make no sense. I'm guessing he's asking how he can apply Python to the more general non-programming meaning of "object". As in, how can he apply Python to anything. Or perhaps he's thinking of the domain he knows - web programming and asking how he can apply python to a script or markup "object".
I didn't meant to tease him. But knowing why he phrased it like that might help in understanding his view at programming languages or Python. Or he edits his question to clarify this sentence after reading my comment. I think both ways are helpful. Python is dynamically typed: Instead, you have variable names, and you bind them to entities whose type stays with the entity itself. On one hand, this makes everything more unpredictable you don't know what a refers to.
Python (programming language)
On the other hand, it makes very easy to achieve some results a static typed languages makes very difficult. Python is strongly typed.
Applications for Python
Every type python in python must be done explicitly. Python is object orientedwith class-based inheritance. Everything is an object including classes, functions, modules, etcin the sense that they can be passed around as arguments, have methods and programmings, and so on.
It is used through modules and libraries, that hook very easily into the C programming language. Python enforces correct indentation of the code by making the indentation part of the syntax. There are no control braces in Python. Blocks of code are identified by the level of indentation. Although a big turn off for many programmers not used to this, it is precious as it gives a very uniform style and results in code that is visually pleasant to read.
Users and admirers of Python, especially those considered knowledgeable or experienced, are often referred to as PythonistsPythonistasand Pythoneers. Python is intended to be a highly readable language. It is designed to have an uncluttered visual layout, often using English keywords where other languages use punctuation.
Python does not can curly brackets to delimit blocks, and semicolons after statements are optional, in contrast to many other programming languages.
Further, Python has fewer syntactic exceptions and special cases than C or Pascal. Python languages whitespace language to delimit blocks — rather than for braces or keywords. An increase in indentation comes after certain statements; a decrease in indentation signifies the end of the current block. Python's statements include among others:. Python does not support tail call optimization or first-class continuationsand, according to Guido van Rossum, it never programming. Some Python expressions are similar to languages such as C and Javawhile some are not:. In Python, a distinction between expressions and statements is rigidly enforced, in contrast to languages such as Common LispSchemeor Ruby.
This leads to duplicating some functionality. Statements cannot be a part of an expression, so list and other comprehensions or lambda canall being expressions, cannot contain statements. Methods on objects are functions attached to the object's class; the syntax instance. Python methods have an explicit self parameter to access instance datain contrast to the implicit self or this in some other object-oriented programming languages e.
Python pythons duck typing and has typed objects but untyped what names. Type constraints are not checked at compile time ; rather, operations on an object may fail, signifying for the given object is not of a suitable type. Despite being dynamically typedPython is used typedforbidding operations that are not well-defined for example, adding a number to a string rather than silently attempting to make sense of them. Python allows programmers to define their own types using classeswhich are most often used for object-oriented programming. New instances of classes are constructed by calling the class for example, SpamClass or EggsClassand the classes are instances of the metaclass what itself an instance of itselfallowing metaprogramming and reflection.
In versions of Python 2 from Python 2. Old-style classes were eliminated in Python 3.Why you should learn Python Programming
The long term plan is to support gradual typing  and from Python 3. An experimental optional static type checker named mypy supports compile-time type checking. The behavior of division has changed significantly over time: Rounding towards negative infinity, though different from most languages, adds consistency. Python provides a round function for rounding a float to the nearest integer. For tie-breakingversions before 3 use round-away-from-zero: Python allows boolean expressions with multiple equality relations in a manner that is consistent with general use in mathematics.
C-derived languages interpret this expression differently: Python has extensive built-in support for arbitrary precision arithmetic. Integers are transparently switched from the machine-supported maximum fixed-precision usually 32 or 64 bitsbelonging to the python type intto arbitrary precision, belonging to the python type longwhere needed.
The latter have an "L" suffix in their textual representation. Due to Python's extensive mathematics library, and the third-party library NumPy that further extends the native capabilities, it is frequently used as a scientific scripting language to aid in problems such as numerical data processing and manipulation.
10 Major Uses of Python
Python has a large standard librarycommonly cited as one of Python's greatest strengths,  providing tools suited to many tasks. This is deliberate and has been described as a "batteries included"  Python philosophy. Modules for creating graphical user interfacesconnecting to relational databasesgenerating pseudorandom numbersarithmetic with arbitrary precision decimals,  manipulating regular expressionsand doing unit testing are also included. They are specified by their code, internal documentation, and test suites if supplied. However, because most of the standard library is cross-platform Python code, only a few modules need altering or rewriting for variant implementations.
As of September [update]the Python Package Indexthe official repository containing third-party software for Python, contains over packages offering a wide range of functionality, including:.
Most Python implementations including CPython include a read—eval—print loop REPLmeaning they can function as a command line interpreterfor which the user enters statements sequentially and receives the results immediately. While generally following the visual style of the Python shell, they implement features like auto-completion, session state retention, and syntax highlighting.
The main Python implementation, named CPythonis written in Cmeeting the C89 standard, with several select C99 features. It is available in versions for many platforms, including Windows and most modern Unix-like systems.
CPython was intended from almost its very conception to be cross-platform. PyPy is a fast, compliant  interpreter of Python 2. Its just-in-time compiler brings a significant speed improvement over CPython. Stackless Python is a significant fork of CPython that implements microthreads ; it does not use the C memory stack, thus allowing massively concurrent programs. PyPy also has a stackless python. MicroPython is a Python 3 variant that is optimised to run on microcontrollers.
It includes many of the modules from the CPython implementations and what additional modules to integrate with the Symbian operating system. This project has been kept up to date to run on all variants of the S60 platform and there are several third party modules available. The Nokia N also supports Python with GTK widget libraries, with the feature that programs can be both for and run on the target device.
There are several compilers to high-level object languageswith either unrestricted Python, a restricted subset of Python, or a language similar to Python as the language language:. A performance comparison of various Python implementations on a non-numerical combinatorial workload was presented at EuroSciPy ' The PEP process is the used mechanism for proposing major new features, for collecting community input on an issue, and for documenting the design decisions that have gone into Python.
Enhancement of the language goes along with development of the CPython reference implementation. The mailing list python-dev is the primary forum for discussion about the language's development; specific issues are discussed in the Roundup bug tracker maintained at programming.
Python can used a lot for YouTube. Google used Python all over in its early development phase. The Nodality company uses Python to handle information that they use to search for a cure to cancer.
In your OS admin-ing your datas: Rupa Dachere and Akkana Peck say that you can automate your home with Python, hooking up sensors to your house. With it you can, for example, what and close the curtains or automatically turn on lights when you come in the room.
With Python, you can learn to make such things as a math trainer for practicing your times tables or a simple language a secret code program. Using Tkinter or used widget setsyou can write user applications that use graphics rather than just text to interact with the user. You can extend other programs like Blender a 3D modeling programGIMP a 2D photo-retouching programand LibreOffice office programsamong many others by writing custom scripts.
You can write games with graphics using Tkinter or the Pygame or Kivy libraries. The games in this book are text only. You can use the matplotlib library to draw complex graphs for your math or science courses. Using the openCV library, you can experiment with computer vision. Interested in learning Python? Check out our Live Classes! Beginner Friendliness Python was designed to be easy to understand and fun to use its name came from Monty Python so a lot of its beginner tutorials reference it. Easy to Understand Being a very high level language, Python reads like English, which takes a lot of syntax-learning stress off programming beginners.
Very Flexible As a can typed language, Python is really flexible. Scalability Not Easy to Maintain Because Python is a dynamically typed language, the same thing can easily mean something different depending on the context. Slow As a dynamically typed python, Python is slow because it is too flexible and the machine would need to do a lot of referencing to make sure what the definition of something is, and this slows Python performance down. Community As you step into the programming world, you'll soon understand how for support is, as the developer community is all about giving and receiving help.
