Witryna23 lut 2024 · Nonlocal variables are defined in the nested function whose scope is not defined. Example: Output: Explanation: From the above program, it can be noticed that the nested function is innerfn(). Inside the innerfn(), you saw the use of a nonlocal keyword to create a nonlocal variable. The innerfn() is defined in the scope of outerfn().
WitrynaWhen a function modifies data outside the local scope, either with the global or nonlocal keyword or by directly modifying a mutable type in place, it’s a kind of side effect similar to when a function modifies one of its arguments.
