The comma is missing.
If you actually wanted to use string replacement, you'd need a pattern with look-behind and look-ahead assertions along the lines of "(?<![A-Za-z0-9_])word(?![A-Za-z0-9_])". Then again, I don't think string replacement is the right tool for the job. You're saying that the file you are operating on in this fashion is a Python script. Why don't you just place something like LAPTOP="10.1.3.4" at the top of that file, or have the script read this information from a configuration file? -Carsten -- http://mail.python.org/mailman/listinfo/python-list
