Python Package Index
open-in-new
<p>The Python Package Index, abbreviated as PyPI and also known as the Cheese Shop (a reference to the <i><a href="/facts/Monty_Python%27s_Flying_Circus/9HlYg0er">Monty Python's Flying Circus</a></i> sketch "<a href="/facts/Cheese_Shop_sketch/StY4StDM">Cheese Shop</a>"),: 8 : 742 is the official third-party <a href="/facts/Software_repository/TlX4RM8Y">software repository</a> for <a href="/facts/Python_(programming_language)/YbuGqofa">Python</a>. It is analogous to the <a href="/facts/CPAN/MB7Iv662">CPAN</a> repository for <a href="/facts/Perl/fx31kjlT">Perl</a>: 36 and to the <a href="/facts/R_package/etUNSDLc">CRAN</a> repository for <a href="/facts/R_(programming_language)/LSrkr8K8">R</a>. PyPI is run by the <a href="/facts/Python_Software_Foundation/KKetSPAS">Python Software Foundation</a>, a charity. Some <a href="/facts/Package_manager/kEX4kx7g">package managers</a>, including <a href="/facts/Pip_(package_manager)/SxNrzmyj">pip</a>, use PyPI as the default source for packages and their dependencies. </p><p>As of 6 May 2024,<a href="https://en.wikipedia.org/w/index.php?title=Python_Package_Index&action=edit">[update]</a> more than 530,000 Python packages are available. </p><p>PyPI primarily hosts Python packages in the form of source archives, called "sdists", or of "wheels" that may contain binary modules from a compiled language. </p><p>PyPI as an index allows users to search for packages by <a href="/facts/Index_term/fRqKUggI">keywords</a> or by <a href="/facts/Filter_(software)/PKwFrEfI">filters</a> against their <a href="/facts/Metadata/qt35z79C">metadata</a>, such as <a href="/facts/Free_software_license/BACv1rju">free software license</a> or compatibility with <a href="/facts/POSIX/mQkSt234">POSIX</a>. A single entry on PyPI is able to store, aside from just a package and its metadata, previous releases of the package, <a href="/facts/Preprocessor/arTRL5RG">precompiled</a> wheels (e.g. containing <a href="/facts/Dynamic-link_library/vySyC1dz">DLLs</a> on Windows), as well as different forms for different <a href="/facts/Operating_system/8XTuvMh2">operating systems</a> and Python versions. </p>
