Checking if a List is Empty: The Pythonic Way In Python, an empty list is considered False in a boolean context, while a non-empty list is considered True. Therefore, the most straightforward and "Pythonic" way to check if a list is empty is simply to use the list in an if statement...
The Pythonlen()is used to get the total number of characters present in the string and check if the length of the string is 0 to identify the string is empty. Actually, thelen()function returns the length of an object. The object can be a string, a list, a tuple, or other objects ...
ifnotmy_list:print("List is empty") This is using theTruth Value Testingin Python, also known as implicit booleaness or truthy/falsy value testing. Among other rules it defines that empty sequences and collections like'', (), [], {}, set(), range(0)are all considered false. ...
