Run a .bat file using python code
PythonBatch FilePython Problem Overview
I try to run a .bat
file in Windows using Python script.
ask.bat
file:
Application.exe work.xml
I write Python code :
import os
os.system("D:\xxx1\xxx2XMLnew\otr.bat ")
Output: when try to run the file its just give a blink of the command prompt, and the work is not performing.
Note: I try with alternate slash also , but it is not working.
And I also want to save output of the file in another file.
Can anyone suggest how can I make the script runnable.

Solution 1 - Python
This has already been answered in detail on SO. Check out this thread, It should answer all your questions: [https://stackoverflow.com/questions/1818774/python-subprocess][1]
I've tried it myself with this code:
batchtest.py
from subprocess import Popen
p = Popen("batch.bat", cwd=r"C:\Path\to\batchfolder")
stdout, stderr = p.communicate()
batch.bat
echo Hello World!
pause
I've got the batchtest.py example from the aforementioned thread. [1]: https://stackoverflow.com/questions/1818774/python-subprocess
Solution 2 - Python
import subprocess
filepath="D:/path/to/batch/myBatch.bat"
p = subprocess.Popen(filepath, shell=True, stdout = subprocess.PIPE)
stdout, stderr = p.communicate()
print p.returncode # is 0 if success
Solution 3 - Python
Replace \ with / in the path
import os
os.system("D:/xxx1/xxx2XMLnew/otr.bat ")

It is better to write
.bat
file in such way that its running is not dependent on current working directory, i.e. I recommend to put this line at the beginning of.bat
file:cd "%~dp0"
-
Enclose filepath of
.bat
file in double quotes, i.e.:os.system('"D:\\x\\so here can be spaces\\otr.bat" ["<arg0>" ["<arg1>" ...]]')
-
To save output of some batch command in another file you can use usual redirection syntax, for example:
os.system('"...bat" > outputfilename.txt')
Or directly in your .bat
file:
Application.exe work.xml > outputfilename.txt
Solution 5 - Python
Probably the simplest way to do this is ->
import os
os.chdir("X:\Enter location of .bat file")
os.startfile("ask.bat")

You are just missing to make it raw. The issue is with "". Adding r before the path would do the work :)
import os
os.system(r"D:\xxx1\xxx2XMLnew\otr.bat")
Solution 7 - Python
So I do in Windows 10 and Python 3.7.1 (tested):
import subprocess
Quellpfad = r"C:\Users\MeMySelfAndI\Desktop"
Quelldatei = r"\a.bat"
Quelle = Quellpfad + Quelldatei
print(Quelle)
subprocess.call(Quelle)
Solution 8 - Python
python_test.py
import subprocess
a = subprocess.check_output("batch_1.bat")
print a
This gives output from batch file to be print on the python IDLE/running console. So in batch file you can echo the result in each step to debug the issue. This is also useful in automation when there is an error happening in the batch call, to understand and locate the error easily.(put "echo off" in batch file beginning to avoid printing everything)
batch_1.bat
echo off
echo "Hello World"
md newdir
echo "made new directory"

If you are trying to call another exe
file inside the bat
-file.
You must use SET Path
inside the bat
-file that you are calling.
set Path should point into the directory there the exe
-file is located:
set PATH=C:\;C:\DOS {Sets C:\;C:\DOS as the current search path.}
