If you have both Python2 and Python3 installed on your Mac  you can use python --version  to check the version of Python2  and python3 --version  to check the version of Python3  However  if only Python3 is installed  then your system might use python instead of python3 for Python3  In this case  you can just use python --version  to check the version of Python3

Take a look at the docs regarding Python on Mac   The version at  System Library Frameworks Python framework is installed by Apple and is used by the system  It is version 3 3 in your case  You can access and use this Python interpreter  but you shouldn t try to remove it  and it may not be the one that comes up when you type  Python  in a terminal or click on an icon to launch it   You must have installed another version of Python  2 7  on your own at some point  and now that is the one that is launched by default   As other answers have pointed out  you can use the command which python on your terminal to find the path to this other installation

You could have multiple Python versions on your macOS   You may check that by command  type or which command  like   which -a python python2 python2 7 python3 python3 6   Or type python in Terminal and hit Tab few times for auto completion  which is equivalent to   compgen -c python   By default python pip commands points to the first binary found in PATH environment variable depending what s actually installed  So before installing Python packages with Homebrew  the default Python is installed in  usr bin which is shipped with your macOS  e g  Python 2 7 10 on High Sierra   Any versions found in  usr local  such as  usr local bin  are provided by external packages   It is generally advised  that when working with multiple versions  for Python 2 you may use python2 pip2 command  respectively for Python 3 you can use python3 pip3  but it depends on your configuration which commands are available   It is also worth to mention  that since release of Homebrew 1 5 0   on 19 January 2018   the python formula has been upgraded to Python 3 x and a python 2 formula will be added for installing Python 2 7  Before  python formula was pointing to Python 2   For instance  if you ve installed different version via Homebrew  try the following command   brew list python python3   or   brew list   grep  python   it ll show you all Python files installed with the package   Alternatively you may use apropos or locate python command to locate more Python related files   To check any environment variables related to Python  run   env   grep  PYTHON     To address your issues       Error  No such keg   usr local Cellar python   Means you don t have Python installed via Homebrew  However double check by specifying only one package at a time  like brew list python python2 python3      The locate database   var db locate database  does not exist    Follow the advice and run   sudo launchctl load -w  System Library LaunchDaemons com apple locate plist   After the database is rebuild  you can use locate command
