TypeError in iPython #3

Open tehfink opened 4 years ago

tehfink commented 4 years ago

Description

Trying to test the output of a cached attribute from the code example results in a TypeError in the iPython interpreter.

What I Did

In [53]: type(instance.value)

TypeError: unsupported operand type(s) for +: 'property' and 'str'

Still having this issue with Python 3.12.2. What's the best way to check if an AwaitableOnly has been initialized? Using something simple like if not instance.value: … doesn't seem to work.
