Batch file that can read and process its own output in realtime? - batch-file

Question

I have a batch file which runs a python script. The python script after completion sends a number like shown below:
I need my batch file to read its own output as it runs and then use this (the number 3 shown in figure below to do some processing
Is this possible with batch?
EDITED FOR CLARITY:
I want to have a script which uses "net use" command.
The output from this specific command is as shown below... which will be printed to cmd window in which script is running ! Now I want my script to read this output ..like if a certain address is found in the already mapped drives list it will do something..like unmap the drive

I don't understand quite well what your purpose is, what has to do python to do with capture the net use command output?
As a rule of thumb, to capture any command output, you must use a for loop (i.e. here capturing clipboard content using powershell
rem get clipboard content into variable
set "psCmd=powershell -Command "add-type -an system.windows.forms; [System.Windows.Forms.Clipboard]::GetText()""
for /F "usebackq delims=" %%# in (`%psCmd%`) do set "clipContent=%%#"
So, in order to grab the output of net use
#echo off
for /f "skip=6 tokens=2,3" %%a in ('net use') do (
echo/%%a | find ":">NUL && echo/Drive letter %%a - Remote name %%b
)
exit/B
But, I suggest that you better use wmic (following two are similar)
#echo off
for /f "useback skip=1 tokens=1,2" %%a in (`"wmic path Win32_LogicalDisk Where DriveType="4" get DeviceID, ProviderName"`) do (
echo/%%a | find ":">NUL && echo/Drive letter %%a - Remote name %%b
)
exit/B
or
#echo off
for /f "useback skip=1 tokens=1,2" %%a in (`"wmic path Win32_MappedLogicalDisk get DeviceID, ProviderName"`) do (
echo/%%a | find ":">NUL && echo/Drive letter %%a - Remote name %%b
)
exit/B
Since, you may add the /node:"some_other_computer_name" switch to wmic and may list mapped drives from any computer on the net, i.e
#echo off
for /f "useback skip=1 tokens=1,2" %%a in (`"wmic /node:"hp-ml110" path Win32_MappedLogicalDisk Where DriveType="4" get DeviceID, ProviderName"`) do (
echo/%%a | find ":">NUL && echo/Drive letter %%a - Remote name %%b
)
exit/B
Hope it helps.
