just an idea: is your text editor really supporting utf-8? In the mail
it is only displayed as '??' which looks for me as the mail editor did
not send the mail as utf. Try to attach a correct text file.

subprocess.Popen(cmd) question

[WolfgangZ]

Hello,

I'm starting some subprocesses inside a loop. The processes run 
independent and dont need any communication between each other. Due to 
memory issues I need to limit the number of running processes to around 
10. How can I insert a break into my loop to wait until some processes 
are finished?

Some minimal examplecode:

import subprocess
for i in range(0,100):
 cmd='ping localhost'
 p=subprocess.Popen(cmd)
 p.wait()

Thanks for any ideas.

Wolfgang

pycrust startup question

[WolfgangZ]

Hi,

I've tried to add " from __future__ import division" to the startup 
script of pycrust. It seems to be imported as division is listed in the 
namespace. But it is somehow not activated.

Any suggestions?

PyCrust 0.9.5
Python 2.5

At least I'm living in a free country and nobody forces me to learn 
python. So I don't fully understand why you HAVE TO learn it. When your 
problems can be solved in a different programming language than you 
should be free to use whatever you like. And also why should it be 
forbidden to create a new programming language? Diversity and 
competition is usually not bad.
