![]() ![]() An empty check on a string is a very common and most-used expression in any programming language including python. ![]() Empty strings are considered as false meaning they are false in a Boolean context. ![]() If the values compared are not equal, then a value of false is returned. In python, there are several ways to check if the string is empty or not. The applications of the Python None object Let’s take some practical examples of using the None object. If the values compared are not equal, then a value of false is. If the values compared are equal, then a value of true is returned. It returns either true or false depending on the result of the operation. So when we passed an empty set to the if condition itll be evaluated to false. Comparing None to any value will return False except None itself. The not equal operator is a relational or comparison operator that compares two or more values (operands). In python, an empty set always evaluates to false. If the values compared are equal, then a value of true is returned. None is not the same as an empty string ( '' ). It returns either true or false depending on the result of the operation. A simple solution to check if a set is empty is using the len() function.

The not equal operator is a relational or comparison operator that compares two or more values (operands). To check if a Variable is not Null in Python, we can use 3 methods: Method 1: variable is not None Method 2: variable None Method 3: if variable: Note: Python programming uses None instead of null. ![]()
