shutil.which(cmd) function returns the path to the executable that would run if you called
cmd in the command line. If there is no such executable, it returns
None. The shutil module is part of the standard library, so you only need to add the statement “
import shutil” to your program without needing to install it first.
Here’s a minimal example that searches for the path of the
'python.EXE' executable on my Windows machine:
import shutil print(shutil.which('python')) # C:\Users\xcent\AppData\Local\Microsoft\WindowsApps\python.EXE
Let’s confirm that the executable is indeed on this location by using the
ls command in my PowerShell to list the directory content:
Let’s test a couple of more executable locations:
>>> shutil.which('cmd') 'C:\\Windows\\system32\\cmd.EXE' >>> shutil.which('find') 'C:\\Windows\\system32\\find.EXE' >>> shutil.which('help') 'C:\\Windows\\system32\\help.EXE'
