effective means to flip boolean values?

[Exsul]

Is there a method or something to easily flip a Boolean value from False to True or vice versa?

You use not to do that, obviously.

ndc85430 idea expressed in code:

>>> spam = True >>> spam = not spam >>> spam False >>> spam = not spam >>> spam True

Another possibility is to use itertools.cycle(). This is useful, if there are more than two values to flip:

>>> from itertools import cycle >>> switch = cycle([True, False]).__next__ >>> spam = switch() >>> spam True >>> spam = switch() >>> spam False >>> spam = switch() >>> spam True >>> switch = cycle(['ON', 'STANDBY', 'OFF']).__next__ >>> spam = switch() >>> spam 'ON' >>> spam = switch() >>> spam 'STANDBY' >>> spam = switch() >>> spam 'OFF' >>> spam = switch() >>> spam 'ON'

Thank you! That looks super useful!
