Though Python is not primarily a functional language, it is able to support functional programming relatively easily because everything in Python is an object. That means that function definitions can be assigned to variables and passed around.How do you use the next function in Python?
Python next() function is used to fetch next item from the collection. It takes two arguments an iterator and a default value and returns an element. This method calls on iterator and throws an error if no item is present. To avoid the error, we can set a default value.Why fclose () is used in C?
