Re: Persistent variable in subprocess using multiprocessing?

I realize that the Queue would be the best way of doing this, however that involves transferring the huge amount of data for each call - my hope was to transfer it once and have it remain in memory for the subprocess across run() calls. On Jul 16, 1:18 pm, Piet van Oostrum wrote: > > mheavner

Re: Why not enforce four space indentations in version 3.x?

However, they are a single logical level of indentation -- I come down fairly solidly on the "tabs" side of the "tabs vs. spaces" argument. My bet is that the problem is this: some people like to format their code in ways that don't work well when you're using tabs. For example, they might want

Hi, Thanks all for the replies. I am working on a cluster of 15 nodes and I have now installed python 3.1 on all of them. I tried installing python2.6 but there was some make error. So, I do not want to give more time in installing 2.4 and rather use 3.1 but for that I need to convert my 2.4 co
