One of my use cases for `for - else` does not involve a `break`: the initialization of the loop variable when the sequence is empty. It is demonstrated by the following transscript: ```pycon >>> for i in range(0): ... pass ... >>> i Traceback (most recent call last): File "<stdin>", line 1, in <module> NameError: name 'i' is not defined >>> for i in range(0): ... pass ... else: i = None ... >>> i >>> ``` For this use case, `else` is perfectly named. -- https://mail.python.org/mailman/listinfo/python-list
