What is a recursive function in Python?

• A function that calls itself

• A function that returns a Boolean value

• A function that performs mathematical operations

• A function that has multiple return values

What is the output of the following code snippet?

    def factorial(n):

        if n == 0:

            return 1

        else:

            return n * factorial(n-1)

    print(factorial(5))

   

• 1

• 5

• 10

• 120

What is the purpose of the "return" statement in a function?

• To end the execution of a function

• To return a value from a function

• To print output from a function

• To define a local variable within a function

What is the purpose of the "return" statement in a function?

• To end the execution of a function

• To return a value from a function

• To print output from a function

• To define a local variable within a function

What is the scope of a variable defined inside a function?

• Global scope

• Local scope within the function

• Both global and local scope

• It is not possible to define variables inside a function

What is the base case in a recursive function?

• The initial condition that ends the recursion

• The final output of the recursive function

• The maximum number of recursive calls allowed

• The condition for starting the recursion

What is the output of the following code snippet?

    def countdown(n):

        if n <= 0:

            return

        print(n)

        countdown(n-1)

    countdown(5)

• 5 4 3 2 1

• 1 2 3 4 5

What is the purpose of a recursive function?

• To perform repetitive tasks efficiently

• To solve complex problems by breaking them down into smaller subproblems

• To create infinite loops

• To execute a block of code repeatedly

Which of the following is an example of a recursive algorithm?

• Linear search

• Binary search

• Bubble sort

• Selection sort

Can a Python function return more than one value simultaneously?

• Yes

• No

• Only if the return values are of the same data type

• Only if the return values are stored in a list or tuple
