As you can see, (x = 2243) assigns the variable name to the integer 2243, then assigns y to this integer object as well. so in essence you're saying if 2243: which is the same as saying 'if ' and anything nonzero, which is True. so basically the following line > string = string + "e" is always being executed. > if x = 2234: > string = string + "p" same with this one. > > how do I create this: > list = [ > (2342,p) > (4234,e) > and so forth, > ] > > so I can use it like this: > > for a in range(10): > If x = list[a][0]: If is invalid. Python is case sensitive. 'if' and 'If' are not the same. Also, you're using an assignment instead of a comparison again. > string = string + list[a][1] > > > ? You could probably solve this easily with a dictionary. -Luke _______________________________________________ Tutor maillist - [email protected] http://mail.python.org/mailman/listinfo/tutor
