Upendra Kumar added the comment: 2. Detecting different versions of Python installed :
For Windows : It is explained in PEP 514 by Steve Dower. Windows has registry keys which can be accessed by winreg or _winreg module. Priority of registry keys : HKEY_CURRENT_USER > HKEY_LOCAL_MACHINE On 64 bit Windows there is another registry key for 32 bit programs, HKEY_LOCAL_MACHINE\Software\Wow6432Node Therefore using registry keys we can know about Python packages installed by enumerating on : 1. HKEY_CURRENT_USER\Software\Python\<Company>\<Tag>\<InstallPath> 2. HKEY_LOCAL_MACHINE\Software\Python\<Company>\<Tag>\<InstallPath> 3. HKEY_LOCAL_MACHINE\Wow6432Node\Python\<Company>\<Tag>\<InstallPath> <Tag> will tell the version number of Python, and in <InstallPath> key there are two more subkeys which will tell the location of Python executable : 1. <Executable Path> 2. <WindowedExecutablePath> For Linux : We can find Python installations in /usr/bin/pythonXYZ For MAC OS : It can be searched for in /Library/Frameworks/ /System/Library/Frameworks If Python was installed by Homebrew : Then the location can be in /usr/local ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue27051> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
