pip (also known by Python 3's alias pip3) is a package-management system written in Python and is used to install and manage software packages. [4] The Python Software Foundation recommends using pip for installing Python applications and its dependencies during deployment. [5] Pip connects to an online repository of public packages, called the ...
In Python, namespaces are defined by the individual modules, and since modules can be contained in hierarchical packages, then namespaces are hierarchical too. [ 12 ] [ 13 ] In general when a module is imported then the names defined in the module are defined via that module's namespace, and are accessed in from the calling modules by using the ...
In software engineering, the module pattern is a design pattern used to implement the concept of software modules, defined by modular programming, in a programming language with incomplete direct support for the concept.
Some package managers, including pip, use PyPI as the default source for packages and their dependencies. [6] [7] As of 6 May 2024, more than 530,000 Python packages are available. PyPI primarily hosts Python packages in the form of source archives, called "sdists", or of "wheels" [8] that may contain binary modules from a compiled language.
Upkg: Package management and build system based on Mono and XML specifications. Used by paldo and previously by ExTiX Linux; MacPorts (for OS X); NetBSD's pkgsrc works on several Unix-like operating systems, with regular binary packages for macOS and Linux provided by multiple independent vendors;
PackageKit runs as a system-activated daemon, named packagekitd, which abstracts out differences between the different systems. A library called libpackagekit allows other programs to interact with PackageKit. [7] Features include: installing local files, ServicePack media and packages from remote sources; authorization using Polkit
Mail is read either through direct access (shell login) or mailbox protocols like POP and IMAP. Unix-based MTA software largely acts to enhance or replace the respective system's native MTA. Microsoft Windows servers do not natively implement e-mail, thus Windows-based MTAs have to supply all the necessary aspects of e-mail-related functionality.
A package import is "a directed relationship between an importing namespace and a package, indicating that the importing namespace adds the names of the members of the package to its own namespace." [2] By default, an unlabeled dependency between two packages is interpreted as a package import relationship. In this relationship, elements within ...
