Message327661
bytes() and bytearray() replace some unexpected exceptions (including MemoryError and KeyboardInterrupt) with TypeError.
1) Exception in __index__.
class X:
def __index__(self):
raise MemoryError
`bytes(X())` results in:
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
TypeError: cannot convert 'X' object to bytes
`bytearray(X())` results in:
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
TypeError: 'X' object is not iterable
This is related to issue29159.
2) Exception in __iter__.
class X:
def __iter__(self):
raise MemoryError
`bytes(X())` results in:
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
TypeError: cannot convert 'X' object to bytes
`bytearray(X())` works correctly (raises a MemoryError).
The proper solution is to replace just a TypeError and allow other exceptions to emerge. |
