--> from collections import deque --> d = deque() --> d += 1 Traceback (most recent call last): File "<stdin>", line 1, in <module> TypeError: 'int' object is not iterable deque should be returning NotImplemented, which would generate a more appropriate error message: TypeError: unsupported operand type(s) for -=: 'collections.deque' and 'int' which is what happens with -=, *=, /=, |=, at which point I stopped testing. |

Please don't replicate the same variant of the issue multiple times. |

This behavior was intended. It was modeled after the behavior for lists. Any change here would break code such as: d = deque() d += 'abc' # This is specially allowed (note, we have a test for it) |
