Hi all, I have two lists that contain strings in the form string + number for example
>>> list1 = [ ' XXX1', 'XXX2', 'XXX3', 'XXX5'] the second list contains strings that are identical to the first list, so lets say the second list contains the following >>> list1 = [ ' XXX1', 'XXX2', 'XXX3', 'XXX6'] and now what ive been trying to do is find the first string that is available, i.e a string that is in neither of the two lists so the following code should only print XXX4 then return. for i in xrange(1,10): numpart = str(1) + str("%04i" %i) str = "XXX" + numpart for list1_elm in list1: if list1_elm == str: break else: for list2_elm in list2: if list2_elm == str: break else: print str return Cheer -- http://mail.python.org/mailman/listinfo/python-list
