Simply import it and ask for a python:>>>frompythonfinderimportFinder>>>f=Finder()>>>f.find_python_version(3,minor=6)PathEntry(path=PosixPath('/home/hawk/.pyenv/versions/3.6.5/bin/python'), _children={}, is_root=False, only_python=False, py_version=PythonVersion(major=3, minor=6, patch=5, is_prerelease=False, is_postrelease=False, is_devrelease=False, version=<Version('3.6.5')>, architecture='64bit', comes_from=PathEntry(path=PosixPath('/home/hawk/.pyenv/versions/3.6.5/bin/python'), _children={}, is_root=True, only_python=False, py_version=None, pythons=None), executable=None), pythons=None)>>>f.find_python_version(2)PathEntry(path=PosixPath('/home/hawk/.pyenv/shims/python2'), ...py_version=PythonVersion(major=2, minor=7, patch=15, is_prerelease=False, is_postrelease=False, is_devrelease=False, version=<Version('2.7.15')>, architecture='64bit', comes_from=PathEntry(path=PosixPath('/home/hawk/.pyenv/shims/python2'), _children={}, is_root=True, only_python=False, py_version=None, pythons=None), executable=None), pythons=None)>>>f.find_python_version("anaconda3-5.3.0")Find a named distribution, such asanaconda3-5.3.0:PathEntry(path=PosixPath('/home/hawk/.pyenv/versions/anaconda3-5.3.0/bin/python3.7m'), _children={'/home/hawk/.pyenv/versions/anaconda3-5.3.0/bin/python3.7m': ...}, only_python=False, name='anaconda3-5.3.0', _py_version=PythonVersion(major=3, minor=7, patch=0, is_prerelease=False, is_postrelease=False, is_devrelease=False,...))PythonFinder can even find beta releases:>>>f.find_python_version(3,minor=7)PathEntry(path=PosixPath('/home/hawk/.pyenv/versions/3.7.0b1/bin/python'), _children={}, is_root=False, only_python=False, py_version=PythonVersion(major=3, minor=7, patch=0, is_prerelease=True, is_postrelease=False, is_devrelease=False, version=<Version('3.7.0b1')>, architecture='64bit', comes_from=PathEntry(path=PosixPath('/home/hawk/.pyenv/versions/3.7.0b1/bin/python'), _children={}, is_root=True, only_python=False, py_version=None, pythons=None), executable=None), pythons=None)>>>f.which('python')PathEntry(path=PosixPath('/home/hawk/.pyenv/versions/3.6.5/bin/python'), _children={}, is_root=False, only_python=False, py_version=PythonVersion(major=3, minor=6, patch=5, is_prerelease=False, is_postrelease=False, is_devrelease=False, version=<Version('3.6.5')>, architecture='64bit', comes_from=PathEntry(path=PosixPath('/home/hawk/.pyenv/versions/3.6.5/bin/python'), _children={}, is_root=True, only_python=False, py_version=None, pythons=None), executable=None), pythons=None)Windows SupportPythonFinder natively supports windows via both thePATHenvironment variable andPEP-514compliant finder which comes by default with python 3. Usage on windows becomes:>>>frompythonfinderimportFinder>>>f=Finder()>>>f.find_python_version(3,minor=6)PythonVersion(major=3, minor=6, patch=4, is_prerelease=False, is_postrelease=False, is_devrelease=False, version=<Version('3.6.4')>, architecture='64bit', comes_from=PathEntry(path=WindowsPath('C:/Program Files/Python36/python.exe'), _children={}, is_root=False, only_python=True, py_version=None, pythons=None), executable=WindowsPath('C:/Program Files/Python36/python.exe'))>>>f.find_python_version(3,minor=7,pre=True)PythonVersion(major=3, minor=7, patch=0, is_prerelease=True, is_postrelease=False, is_devrelease=False, version=<Version('3.7.0b5')>, architecture='64bit', comes_from=PathEntry(path=WindowsPath('C:/Program Files/Python37/python.exe'), _children={}, is_root=False, only_python=True, py_version=None, pythons=None), executable=WindowsPath('C:/Program Files/Python37/python.exe'))>>>f.which('python')PathEntry(path=WindowsPath('C:/Python27/python.exe'), _children={}, is_root=False, only_python=False, py_version=None, pythons=None)Finding ExecutablesPythonFinder also provideswhichfunctionality across platforms, and it uses lazy loading and fast-returns to be performant at this task.>>>f.which('cmd')PathEntry(path=WindowsPath('C:/windows/system32/cmd.exe'), _children={}, is_root=False, only_python=False, py_version=None, pythons=None)>>>f.which('code')PathEntry(path=WindowsPath('C:/Program Files/Microsoft VS Code/bin/code'), _children={}, is_root=False, only_python=False, py_version=None, pythons=None)
