1. Consider the following function:

    def square(num):
        num_squared = num ** 2
        return num_squared
   

   Which line of codes is the function’s signature?

   Answer: def square(num):

2. What is the output of the following function call?

    def fun1(name, age=20):
        print(name, age)
       
    fun1('Emma', 25)
   

   Answer: Emma 25

3. What is the output of the following display_person() function call?

    def display_person(*args):
        for i in args:
            print(i)
   
    display_person(name="Emma", age="25")
   

   Answer: TypeError: display_person() got an unexpected keyword argument 'name'

4. What is the output of the add() function call?

    def add(a, b):
        return a+5, b+5
       
    result = add(3, 2)
    print(result)
   

   Answer: (8, 7)

5. Select which is true for Python function:

   • A Python function can return only a single value
   • A function can take an unlimited number of arguments
   • A Python function can return multiple values
   • Python function doesn’t return anything unless and until you add a return statement

   Answer:

   • A function can take an unlimited number of arguments
   • A Python function can return multiple values

6. Write a program to create a function that takes two arguments, name and age, and print their value.

    def print_name_and_age(name, age):
        print("Name:", name)
        print("Age:", age)
           
    # Call the function
    print_name_and_age("John", 30)
   

7. Write a program to create function func1() to accept a variable length of arguments and print their value.

    def func1(*args):
        for arg in args:
            print(arg)
   

8. Write a program to create function calculation() such that it can accept two variables and calculate addition and subtraction. Also, it must return both addition and subtraction in a single return call.

    def calculation(num1, num2):
        add = num1 + num2
        sub = num1 - num2
        return add, sub
       
    # Call the function
    result = calculation(10, 5)
    print(result)
   

9. Write a program to create a recursive function to calculate the sum of numbers from 0 to 10.

    def recursive_sum(n):
        if n == 0:
            return 0
        else:
            return n + recursive_sum(n-1)
   
    # Call the recursive_sum function with argument 10 and print the result
    result = recursive_sum(10)
    print(result)
   

10. Generate a Python list of all the even numbers between 4 to 30.

    even_numbers = []
    for num in range(4, 31):
        if num % 2 == 0:
            even_numbers.append(num)
    print(even_numbers)
