I've tried this and I cannot figure out why this does not work. I figure this has something to do with order of operations. I figured someone would know exactly why it doesn't work. Wouldn't this start inside parens then from left to right?
open(item,'w').write(open(item,'r').read().replace(' ',''))
I tried this on the shell just trying to do some quick text replacement because I could figure out how to get awk to do it, and I didn't want to spend 5 hours RTFM. I got it to work by breaking it up to several statements, but I would like to know.
It's quite easy: evaluation starts from left to right. The program opens item for writing (thus deleting it), creating a file object, then executes its write method on the argument in the parens. However, since at that point item is now empty, there is nothing to read from.
