Python Packaging User Guide. As a general-purpose programming language, Python is designed to be used in many ways. You can build web sites or industrial robots or a game for your friends to play, and much more, all using the same core technology.
It might seem strange to think about packaging before writing code, but this process does wonders for avoiding future headaches.
Read on to choose the best technology for your next project. Thinking about deployment. Packaging Python libraries and tools. Python source distributions. Python binary distributions. Packaging Python applications. Depending on a framework. Web browsers and mobile applications, from where does binary options work.
Depending on a pre-installed Python. Depending on a separate software distribution ecosystem. Bringing your own Python executable. Bringing your own userspace. Bringing your own kernel. Bringing your own hardware, from where does binary options work.
Operating system packages. Will your software be installed by other developers doing software development, operations people in a datacenter, or a less software-savvy group? Is your software intended to run on servers, desktops, mobile clients phones, tablets, etc. Packaging is all about target environment and deployment experience. There are many answers to the questions above and each combination of circumstances has its own solutions. With this information, the following overview will guide you to the packaging technologies best suited to your project.
You may have heard about PyPI, setup. pyand wheel files. The following approaches to packaging are meant for libraries and tools used by technical audience in a development setting.
A Python file, provided it only relies on the standard library, can be redistributed and reused. This is great for sharing simple scripts and snippets between people who both have compatible Python versions such as via email, StackOverflow, or GitHub gists.
There are even some entire Python libraries that offer this as an option, such as bottle. py and boltons. Any directory containing Python files can comprise an Import Package. Because packages consist of multiple files, they are harder to distribute. Most protocols support transferring only one file at a time when was the last time you clicked a link and it downloaded multiple files?
gz files containing one or more packages or modules. If your code is pure-Python, and you only depend on other Python packages, you can go here to learn more. If you rely on any non-Python code, or non-Python packages such as libxml2 in the case of lxmlor BLAS libraries in the case of numpyyou will need to use the format detailed in the next section, which also has many advantages for pure-Python libraries.
Python and PyPI support multiple distributions providing different implementations of the same package. For instance the unmaintained-but-seminal PIL distribution provides the PIL package, and so does Pillowan actively-maintained fork of PIL! Not all developers have the right tools or experiences to build these components written in these compiled languages, so Python created the Wheela package format designed to ship libraries with compiled artifacts.
From where does binary options work distributions are best when they come with source distributions to match. Python and PyPI make it easy to upload both wheels and sdists together. Just follow the Packaging Python Projects tutorial. Excerpted from The Packaging Gradient Based on our introduction, you would be correct to infer these built-in approaches only target environments which have Python, and an audience who knows how to install Python packages.
With the variety of operating systems, configurations, and people out there, this assumption is only safe when targeting a developer audience.
Libraries are building blocks, not complete applications. The next few sections organize these application packaging options according to their dependencies on the target environment, so you can choose the right one from where does binary options work your project. Some types of Python applications, like web site backends and other network services, are common enough that they have frameworks to enable their development and packaging.
Other types of applications, like dynamic web frontends and mobile clients, are complex enough to target that a framework becomes more than a convenience. Some frameworks include a deployment system which wraps the technologies outlined in the rest of the guide. If you ever wonder how these platforms and frameworks work under the hood, you can always read the sections beyond. Google App Engine.
In all these setups, the platform takes care of packaging and deployment, as long as you follow their patterns. Most software does not fit one of these templates, hence the existence of all the other options below. These days you can write a mobile app or web application frontend in Python. While the language may be familiar, the packaging and deployment practices are brand new. If you are not interested in using a framework or platform, or just wonder about some of the technologies and techniques utilized by the frameworks above, continue reading below.
Included by default in most Linux and Mac operating systems for many years now, you can reasonably depend on Python preexisting in your data centers or on the personal machines of developers and data scientists.
PEX Python EXecutable. zipapp does not help manage dependencies, requires Python 3. shiv requires Python 3. From where does binary options work all the approaches here, depending on a pre-installed Python relies the most on the target environment. Of course, this also makes for the smallest package, as small as single-digit megabytes, or even kilobytes. In general, decreasing the dependency on the target system increases the size of our package, so the solutions here are roughly arranged by increasing size of output.
For a long time many operating systems, including Mac and Windows, from where does binary options work, lacked built-in package management. Developers long sought remedies, and in this struggle, emerged with their own package management solutions, such as Homebrew.
The most relevant alternative for Python developers is a package ecosystem called Anaconda. Anaconda is built around Python and is increasingly common in academic, analytical, and other data-oriented environments, even making its way into server-oriented environments. Building libraries and applications with conda. Transitioning a native Python package to Anaconda. A similar model involves installing an alternative Python distribution, but does not support arbitrary operating system-level packages:.
ActiveState ActivePython. Computing as we know it is defined by the ability to execute programs. Every operating system natively supports one or more formats of program they can natively execute. There are many techniques and technologies which turn your Python program into one of these formats, most of which involve embedding the Python interpreter and any other dependencies into a single executable file.
This approach, called freezingoffers wide compatibility and seamless user experience, though often requires multiple technologies, and a good amount of effort. pyInstaller - Cross-platform. constructor - For command-line installers. py2app - Mac only. osnap - Windows and Mac. pynsist - Windows only. Most of the above imply single-user deployments. For multi-component server applications, see Chef Omnibus.
An increasing number of operating systems — including Linux, Mac OS, and Windows — can be set up to run applications packaged as lightweight images, using a relatively modern arrangement often referred to as operating-system-level virtualizationor containerization.
These techniques are mostly Python agnostic, because they package whole OS filesystems, not just Python or Python packages. Adoption is most extensive among Linux servers, where the technology originated and where the technologies below work best:. Most operating systems support some form of classical virtualization, running applications packaged as images containing a full operating system of their own.
Running these virtual machines, or VMs, is a mature approach, widespread in data center environments. These techniques are mostly reserved for larger scale deployments in data centers, though certain complex applications can benefit from this packaging.
Technologies are Python agnostic, and include:. VHDAMIfrom where does binary options work, and other formats. OpenStack - A cloud management system in Python, with extensive VM support. The most all-encompassing way to ship your software would be to from where does binary options work it already-installed on some hardware, from where does binary options work.
Whereas the virtual machines described above are primarily reserved for the tech-savvy, you can find hardware appliances being used by everyone from the most advanced data centers to the youngest children. They plug and play, and you can call it a day.
The simplified gamut of technologies used to package From where does binary options work applications. The sections above can only summarize so much, and you might be wondering about some of the more conspicuous gaps. As mentioned in Depending on a separate software distribution ecosystem above, some operating systems have package managers of their own.
