Find full path of the Python interpreter? (3 answers)

Closed 3 years ago.

I have several software packages that install various installs of Python. For example:

C:\Python27\ArcGIS10.1
C:\Python27\ArcGIS10.2
C:\Python27|ArcGISx6410.1

Using sys.version does not work for my case since I need to know where the actual install is located, not the version.

How can I determine which install my Python interpreter is using?

回答1:

What you want is sys.executable, which will give the path to actual interpreter executable.
