Python: naming of boolean/flag class attributes [closed]

Question

Coding style question: What is the recommended way of naming flag class attributes, i.e. attributes being True or False. Styles I can think of are:

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

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

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

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

Answer 1

Considering that booleans are mostly used in coditions, the second way seems most appropriate.

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