wmic call in python return invalid query error

I'm trying to create a python executable that will run multiple wmic calls to check the versions of portable executables.

The following code works in the command prompt, so I attempted to run the same line from python

wmic datafile where name="C:\\Program Files\\Internet Explorer\\iexplore.exe" get Version /value

Python Code:

import subprocess

spath = r'C:\Program Files\Internet Explorer\iexplore.exe'
cargs = ["wmic","datafile","where", r'name="{0}"'.format(spath), "get", "Version", "/value"]

process = subprocess.check_output(cargs)

I get the following error

---------------------------------------------------------------------------
CalledProcessError                        Traceback (most recent call last)

    709     return CompletedProcess(process.args, retcode, stdout, stderr)

CalledProcessError: Command '['wmic', 'datafile', 'where', 'name="C:\\Program Files\\Internet Explorer\\iexplore.exe"', 'get', 'Version', '/value']' returned non-zero exit status 2147749911

The command at the end of the error message looks correct to me. Where am I going wrong?

Solution

When executing the query from console (Cmd), the BackSlashes in the path are doubled (escaped):
wmic datafile where name="C:\\Program Files\\Internet Explorer\\iexplore.exe" get Version /value

According to [MS.Learn]: WHERE Clause (WMI) (emphasis is mine):

You may use string literals, such as "NTFS", in a WHERE clause. If you wish to include the following special characters in your string, you must first escape the character by prefixing the character with a backslash (\):

backslash (\)

double quotes (\")

single quotes (\')

Do the same thing in Python:

>>> import subprocess as sp
>>>
>>> spath = r"C:\\Program Files\\Internet Explorer\\iexplore.exe"
>>> cargs = ("wmic", "datafile", "where", "name=\"{:s}\"".format(spath), "get", "Version", "/value")
>>> process = sp.check_output(cargs)
>>> process.strip().decode()
'Version=11.0.16299.15'
