Steven D'Aprano added the comment: This is a bug in your code, not Python, and the error tells you how to fix it. You have to indent the block.
>>> while b < 1000: ... print(b, end=',') ... a, b = b, a+b Remember to press TAB or spacebar inside indented blocks. You should work through the tutorial. https://docs.python.org/3/tutorial/index.html By the way, you say page 16 of which documentation? Are you reading from a book? Which book? ---------- nosy: +steven.daprano resolution: -> not a bug stage: -> resolved status: open -> closed _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue30753> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
