Python True, com. In Python Programming, every value is either evaluated as True or False. Any value that is evaluated as a True boolean type is considered Truthy. Programming with Python opens up numerous possibilities for you, but one of the fundamental questions you need to clarify is: What is considered true or false? However, Python gives a Truth value to objects, even without building a conditional expression. Should it be like this? Are there other ways to By default, an object is considered true unless its class defines either a __bool__() method that returns False or a __len__() method that returns zero, when called with the object.
