looks like part of the python language reference. It goes a little further and explains what try1_stmt and try2_stmt actually suppose to mean: http://docs.python.org/reference/compound_stmts.html#the-try-statement try_stmt ::= try1_stmt | try2_stmt try1_stmt ::= "try" ":" suite ("except" [expression [("as" | ",") target]] ":" suite)+ ["else" ":" suite] ["finally" ":" suite] try2_stmt ::= "try" ":" suite "finally" ":" suite Let me try to rephrase it: "a try statement is either of try-except-else-finally or of try-finally form". This notation is used to formally describe language syntax: http://docs.python.org/reference/introduction.html#notation best, Michael
