Why is there a difference between running one line like "a=1;b=1" and two lines like "a=1 \n b=1"? Does it decide to locate memory in different types depend on a code? Ah okay! In that case, I'm guessing this is going to be an oddity of the IDLE system, because it's compiling each line separately. When you put it on a single line, it's saving some trouble by sharing the constant; when you do them separately, it doesn't optimize like that. Chris Angelico
