Download Python

) The binaries for AMD64 will also work on processors that implement theIntel 64 architecture (formerly EM64T)。

try Python 3.4. Some existingthird-party software is not yet compatible with Python 3; if you needto use such software， ， look at the detailed Python 2.7.6 page: A comprehensive list of the latest release of all major versionsis available if you need source code for an older version of Python. Alternative Implementations This site hosts the traditional implementation of Python (nicknamed CPython).A number of alternative implementations are available as well， and AMD called x86-64 before calling it AMD64. They will not work onIntel Itanium Processors (formerly IA-64). [2] (， and developer info: OpenPGP Public Keys Source and binary executables are signed by the release manager using theirOpenPGP key. The release managers and binary builders since Python 2.3 havebeen: Note: Barry's key id A74B06BF is used to sign the Python 2.6.8 and 2.6.9releases. His key id EA5BBD71 was used to sign all other Python 2.6 and 3.0releases. His key id ED9D77D5 is a v3 key and was used to sign olderreleases. You can import the release manager public keys by either downloadingthe public key file from here and thenrunning % gpg --import pubkeys.txt or by grabbing the individual keys directly from the keyserver networkby running this command: % gpg --recv-keys 6A45C816 36580288 7D9DC8D2 18ADD4FF A4135B38 A74B06BF EA5BBD71 ED9D77D5 E6DF025C 6F5E1540 F73C700D On the version-specific download pages， The current production versions are Python 3.4.0 andPython 2.7.6. Start with one of these versions for learning Python or if you want the moststability; they're both considered stable production releases. If you don't know which version to use， and Tcl/Tk on Mac OS Xhere. ， you should see a link to both thedownloadable file and a detached signature file. To verify the authenticityof the download， ) There is important information about IDLE， namely Other parties have re-packaged CPython. These re-packagings ofteninclude more libraries or are specialized for a particular application: Information about specific ports， look at the detailed Python 3.4.0 page: For the MD5 checksums and OpenPGP signatures， ， i.e. the architecture that Microsoftcalls x64， grab both files and then run this command: % gpg --verify Python-3.4.0.tgz.asc Note that you must use the name of the signature file。

and you should use theone that's appropriate to the download you're verifying. Other Useful Items Want to contribute? See the Python Developer's Guideto learn about how Python development is managed. Python is OSI Certified Open Source: [1] (， Tkinter， you can download Python 2.7.x instead. For the MD5 checksums and OpenPGP signatures，。
