In most languages, the answer is that the = operator associates right to left, even though most other operators associate left to right. (That's how C does it, for instance.) But in Python, I believe it's actually one operator taking several parameters, because = is not an expression. In any case, you can safely treat = as an exception to the left-to-right rule. There are other exceptions too - note the comments in http://docs.python.org/reference/expressions.html#summary - there's not many RTL operators in Python, only those that make sense that way. :) ChrisA
