Python: assigning class attributes to boolean / flag

Question

Question about coding style. What is the recommended way to assign the attributes of a flag class to a name, that is, Trueor attributes False. The styles I can think of are as follows:

• class MyClass: def my_method(self): self.request = False

• class MyClass: def my_method(self): self.is_request = False

• class MyClass: def my_method(self): self.request_flag = False

PEP8 does not seem to give a firm recommendation. Is there a canonical way to do this?

Answer 1

Given that booleans are mainly used in codes, the second option seems most appropriate.

o = MyClass()
...
if o.is_request: # very intuitive
    # it a request
