You can checkout complete python script and more Python examples from our GitHub Repository . One value is True (others are False), any() returns True. All values are False, any() returns False. The basic rules are: Values that evaluate to False are considered Falsy. Example sequence types in Python: Lists String Tuple any() function is a part of Python … That’s all for python any() function examples. non-zero or non-empty). Notice that second list any() function output is False and boolean value is retrieved for all the objects in the list.

Python provides two built-ins functions for “AND” and “OR” operations are All and Any functions. For example, the expression 1 <= 2 is True, while the expression 0 == 1 is False.Understanding how Python Boolean values behave is important to programming well in Python. In programming you often need to know if an expression is True or False. Similarly, we can check if a variable is not True using one of the following methods: Python any() function. Boolean Strings.
