Hi My name is Juan Carlos Rodrigo, and I love Python. It is the most impressive and usefull language that I have ever seen.
I am studing, at http://www.uoc.edu, an Information Technology Postgraduate. And I have programmed some REXX applications in my past Jobs (So I love python, no more ENDS). This is my Graduate final project http://ip.xpyro.com made in mod_python. I love mod_python too. Please don't crash my AMD making queries. :| --------8<--------8<--------8<--------8<--------8<--------8<-------- Python 2.4 | 7.3 The for statement: ----------------------------------- for_stmt ::= "for" target_list "in" expression_list ":" suite ["else" ":" suite] New for statement: ------------------ for_stmt ::= "for" target_list "in" expression_list [ "and" expression ] ":" suite ["else" ":" suite] ** If the expression evaluates to False before entering the for, jump else. ** If the expression is evaluated to False after the first iteration, break. So ¿What we can do with this new for?, and ¿It is going to avoid line exceed?: "My second remark is that our intellectual powers are rather geared to master static relations and that our powers to visualize processes evolving in time are relatively poorly developed." [1] It is easier if we see it beforehand: ------------------------------------- leave = False alist = [1,2,3,3,4,5,6,7,8,9] for item in alist and not leave: if item is 1: leave = True Avoiding code exceed: --------------------- a = 1 b = 2 c = 3 alist = [1,2,3,4,5,6,7,8,9] for item in alist and a < 2 and b < 3 and c < 4: if item == 3: a += 1 if item == 2: b += 1 if item == 1: c += 1 print "%d %d %d" % (a,b,c) # three lines off (25% less on breaks) Other features and the else: ---------------------------- alist = [1,2,3] enter = False if list[0] == 4: enter = True for item in alist and enter: print item else: print "No account" The real problem: ----------------- "The exercise to translate an arbitrary flow diagram more or less mechanically into a jump-less one, however, is not to be recommended." [1] Ok, it's not recommended, at large, but Python should make it possible, and then the people will choose. [1] Go To Statement Considered Harmful Edsger W.
