You might find the functional programming topic in my tutorial interesting for a comparison. Look at the subsection "Short Circuit Evaluation" for some relevant examples. > I did not understood >>> x = 5 >>> x and 1 >1 >>> y = 0 >>> y and 1 >0 > > How 5 and 1 means 1 and 0 and 1 means 0 In Python any non zero value is considered True. So 5 and 1 are two true values and True and True = True whereas 0 and 1 means: False and True = False (ie zero) Are you familiar with Trutrh tables and the concepts of Boolean Logic? If not you may need some further explanation. If so a reasonable explanation appears on Wikipedia: http://en.wikipedia.org/wiki/Truth_table HTH, Alan G Author of the learn to program web tutor http://www.freenetpages.co.uk/hp/alan.gauld _______________________________________________ Tutor maillist - Tutor@python.org http://mail.python.org/mailman/listinfo/tutor
