Python's all (): Check Your Iterables for Truthiness

In the first example, the input list contains regular Python objects, including a string, a number, and a dictionary.In this case, all_true() returns False because the dictionary is empty and evaluates to false in Python. To perform truth value testing on objects, Python has an internal set of rules for objects that evaluate as false:. Inherently negative constants, like None and False
