Loops in List

[Skaperen]

it had been my understanding that print() would apply repr() to any non-string argument it got.

It does. The error happens before that point. First it evaluates the argument it gets, then it applies repr. The error comes in the evaluation, when + listA[i] tries to add an integer to a string.

Edit: Didn't think it through. print applies str() to any non-string argument it gets. Typing an argument into the interactive console gives the repr().

my bad for blaming it on print().  the OP was building a big string with an int in there and i didn't look at the code close enough to see that.  separate args given to print() works, too.

now you guys need to advise the OP what is the best way to code this to avoid that perl-ism mentioned earlier.
