I should add that *if the wait times out* it still could be the case that your answer has arrived but that the notify occured a microsecond after the timeout. So knowing if the timeout occurred really doesn't tell you much. It's just a way to prevent infinite waiting. -- Piet van Oostrum URL: htt

Re: creating my own logwatch in python

A few code critiques: - Your code is not very help friendly because it can not be run, so I have to deadlist debug it. - There are various syntax errors in the code: - for example: file is not defined when you invoke tail(file) - You are overshadowing a built-in type 'file' by that name,

Suppose that 'xor' returns the value that is true when only one value is true, and False otherwise. This definition of xor doesn't have the standard associative property, that is, (a xor b) xor c will not necessarily equal a xor (b xor c) To see that this is the case, let a= 1, b= 2, and c= 3
