trong>Mr Verity (Eric Idle): Can I help you, sir?
Husband: Yes, we’d like a bed, a double bed, and I wondered if you’d got one for about fifty pounds.
Verity: Oh no, I’m afraid not, sir. Our cheapest bed is eight hundred pounds, sir.
Husband and Wife: Eight hundred pounds?
Lambert: Excuse me, sir, but before I go, I ought to have told you that Mr Verity does tend to exaggerate. Every figure he gives you will be ten times too high.
Husband: I see.
Lambert: Otherwise he’s perfectly all right.
Husband: I see. Er… your cheapest double bed then is eighty pounds?
Verity: Eight hundred pounds, yes, sir.
Husband: I see. And how wide is it?
Verity: It’s sixty feet wide.

3.6. Additional modules¶

Even though Python aims to be portable among all platforms, there are features
that are unique to Windows. A couple of modules, both in the standard library
and external, and snippets exist to use these features.

The Windows-specific standard modules are documented in
.

3.6.1. PyWin32

The PyWin32 module by Mark Hammond
is a collection of modules for advanced Windows-specific support. This includes
utilities for:

  • Component Object Model (COM)
  • Win32 API calls
  • Registry
  • Event log
  • Microsoft Foundation Classes (MFC)
    user interfaces

PythonWin is a sample MFC application
shipped with PyWin32. It is an embeddable IDE with a built-in debugger.

3.6.2. cx_Freeze

cx_Freeze is a
extension (see ) which wraps Python scripts into
executable Windows programs ( files). When you have done this,
you can distribute your application without requiring your users to install
Python.

Достоинства и недостатки

Теперь, когда мы разобрались с теорией, установили Python на компьютер, а также поговорили, как научиться с ним работать, давайте рассмотрим сильные и слабые стороны данного языка программирования по отношению к аналогам.

Плюсы:

  • Данный интерпретатор реализован на любых операционных системах. Работать с Python очень легко в Linux, Microsoft Windows 10 64-Bit, а также MacOS. В двух последних ОС язык программирования устанавливается в качестве модуля.
  • Расширяемость языка. При помощи различных фреймворков и модулей Python можно улучшать, добавляя в него новые возможности. Это является вторым важным достоинством.
  • Наличие большого количества подключаемых модулей.

Минусы:

Медлительность при работе.

Hello World tutorial for using Python with VS Code

The VS Code team has put together a great tutorial walking through how to create a Hello World program with Python, run the program file, configure and run the debugger, and install packages like matplotlib and numpy to create a graphical plot inside a virtual environment.

  1. Open PowerShell and create an empty folder called «hello», navigate into this folder, and open it in VS Code:

  2. Once VS Code opens, displaying your new hello folder in the left-side Explorer window, open a command line window in the bottom panel of VS Code by pressing Ctrl+` (using the backtick character) or selecting View > Terminal. By starting VS Code in a folder, that folder becomes your «workspace». VS Code stores settings that are specific to that workspace in .vscode/settings.json, which are separate from user settings that are stored globally.

  3. Continue the tutorial in the VS Code docs: .

Установка Git (необязательно)Install Git (optional)

Если вы планируете совместно работать над кодом Python с другими пользователями или размещать проект на сайте с открытым исходным кодом (например, GitHub), примите во внимание, что VS Code поддерживает .If you plan to collaborate with others on your Python code, or host your project on an open-source site (like GitHub), VS Code supports. Вкладка системы управления версиями в VS Code отслеживает все изменения и содержит общие команды Git (добавление, фиксация, принудительная отправка, извлечение) прямо в пользовательском интерфейсе.The Source Control tab in VS Code tracks all of your changes and has common Git commands (add, commit, push, pull) built right into the UI

Сначала необходимо установить Git для включения панели управления версиями.You first need to install Git to power the Source Control panel.

  1. Скачайте и установите Git для Windows с веб-сайта git-scm.Download and install Git for Windows from the git-scm website.

  2. В комплект входит мастер установки, который задает вам ряд вопросов о параметрах установки Git.An Install Wizard is included that will ask you a series of questions about settings for your Git installation. Рекомендуется использовать все параметры по умолчанию, если у вас нет конкретной причины изменить какой-либо из них.We recommend using all of the default settings, unless you have a specific reason for changing something.

  3. Если вы никогда не использовали Git, обратитесь к руководствам по GitHub. Они помогут вам приступить к работе.If you’ve never worked with Git before, GitHub Guides can help you get started.

Описание и возможности Python

Python – это функциональный язык программирования, основной список возможностей которого можно охарактеризовать примерно следующим образом:

  • Web-разработка. Для написания сайтов очень часто используется фреймворки на базе Python, например, Django или Flask. Это сильно ускоряет процесс написания кода и в конечном итоге делает ресурс более быстрым и функциональным. В данном случае рассматриваемый сегодня язык программирования приходит на смену таким китам, как PHP или JavaScript.
  • Машинное обучение (Data Science). Данная тема близка к искусственному интеллекту, который так давно пытаются создать люди. Немалую роль в данном процессе занимает Python.
  • Автоматизация процессов. В этом случае Python применяется для написания скриптов, Которые будут выполнять всю работу или ее часть.

OpenPGP Public Keys

Source and binary executables are signed by the release manager or binary builder using their
OpenPGP key. Release files for currently supported releases are signed by the following:

  • Pablo Galindo Salgado (3.10.x and 3.11.x source files and tags) (key id: 64E628F8D684696D)
  • Steve Dower (Windows binaries) (key id: FC62 4643 4870 34E5)
  • Łukasz Langa (3.8.x and 3.9.x source files and tags) (key id: B269 95E3 1025 0568)
  • Ned Deily (macOS binaries, 3.7.x / 3.6.x source files and tags) (key ids: 2D34 7EA6 AA65 421D, FB99 2128 6F5E 1540, and Apple Developer ID DJ3H93M7VJ)
  • Larry Hastings (3.5.x source files and tags) (key id: 3A5C A953 F73C 700D)
  • Benjamin Peterson (2.7.z source files and tags) (key id: 04C3 67C2 18AD D4FF and A4135B38)

Release files for older releases which have now reached end-of-life may have been signed by one of the following:

  • Anthony Baxter (key id: 0EDD C5F2 6A45 C816)
  • Georg Brandl (key id: 0A5B 1018 3658 0288)
  • Martin v. Löwis (key id: 6AF0 53F0 7D9D C8D2)
  • Ronald Oussoren (key id: C9BE 28DE E6DF 025C)
  • Barry Warsaw (key ids: 126E B563 A74B 06BF, D986 6941 EA5B BD71, and ED9D77D5)

You can import a person’s public keys from a public keyserver network server
you trust by running a command like:

or, in many cases, public keys can also be found
at keybase.io.
On the version-specific download pages, you should see a link to both the
downloadable file and a detached signature file. To verify the authenticity
of the download, grab both files and then run this command:

Note that you must use the name of the signature file, and you should use the
one that’s appropriate to the download you’re verifying.

(These instructions are geared to
GnuPG and Unix command-line users.)

Call to action

We strongly encourage maintainers of third-party Python projects to test with 3.9 during the beta phase and report issues found to the Python bug tracker as soon as possible. While the release is planned to be feature complete entering the beta phase, it is possible that features may be modified or, in rare cases, deleted up until the start of the release candidate phase (2020-08-10). Our goal is have no ABI changes after beta 5 and as few code changes as possible after 3.9.0rc1, the first release candidate. To achieve that, it will be extremely important to get as much exposure for 3.9 as possible during the beta phase.

Please keep in mind that this is a preview release and its use is not recommended for production environments.

And now for something completely different

href=»http://www.montypython.net/scripts/galaxy.php»>Our universe itself keeps on expanding and expanding,
In all of the directions it can whiz;
As fast as it can go, at the speed of light, you know,
Twelve million miles a minute and that’s the fastest speed there is.
So remember, when you’re feeling very small and insecure,
How amazingly unlikely is your birth;
And pray that there’s intelligent life somewhere out in space,
‘Cause there’s bugger all down here on Earth!
