Windows - running .py directly vs running python b

问题:

I have a python script that uses subprocess:

import subprocess
print "Running stuff"
subprocess.check_call(["do_stuff.bat"])
print "Stuff run"

If this was named blah.py, and I run (from a command prompt):

python blah.py

I will get the output from do_stuff.bat (or whatever I run).

If this is run as:

blah.py

Then I do not get output from do_stuff.bat, only the print statements.

So far seen on windows Server 2003. Python version 2.5.2 (stuck there for various reasons). Looking at the associated file type action I see:

Python.File="C:\Python25\python.exe" "%1" %*

So can anyone explain the difference?

回答1:

I had common problem using threads, but all of my code was in python. Threads can not write to standard output using print. Just main thread could do that. I used somethnig like this

import sys
sys.stdout.write("this was printed by thread")

I know that probably it wont help you with bat file...
