  1. Aug 2, 2022 · This Python functions exercise aims to help Python developers to learn and practice how to define functions. Also, you will practice how to create and use the nested functions and the function arguments effectively.

    • Python function that prints a text. The statements in the function get executed only when we call the function. The function definition should be written before the function call.
    • Python function that accepts two numbers as arguments and returns the sum. Functions can take arguments (one or more). Functions can return a value to the main method.
    • Python function that accepts different values as parameters and returns a list. def myFruits(f1,f2,f3,f4): FruitsList = [f1,f2,f3,f4] return FruitsList output = myFruits("Apple","Bannana","Grapes","Orange") print(output)
    • Python function that returns a dictionary. def myAnimals(a1,a2,a3): Animalgroup = {'Kitten':a1,'Puppy':a2,'Pup':a3} return Animalgroup output = myAnimals("Cat","Dog","Rat") print(output)
    • Create a Function. Let's create our first function. def greet(): print('Hello World!') Here are the different parts of the program: Here, we have created a simple function named greet() that prints Hello World!
    • Calling a Function. In the above example, we have declared a function named greet(). def greet(): print('Hello World!') If we run the above code, we won't get an output.
    • Example: Python Function Call. def greet(): print('Hello World!') # call the function greet() print('Outside function') Output. Hello World! Outside function.
    • Python Function Arguments. Arguments are inputs given to the function. def greet(name): print("Hello", name) # pass argument greet("John") Sample Output 1.
    • Write a Python function to find the maximum of three numbers. Click me to see the sample solution.
    • Write a Python function to sum all the numbers in a list. Sample List : (8, 2, 3, 0, 7) Expected Output: 20. Click me to see the sample solution.
    • Write a Python function to multiply all the numbers in a list. Sample List : (8, 2, 3, -1, 7) Expected Output: -336. Click me to see the sample solution.
    • Write a Python program to reverse a string. Sample String : "1234abcd" Expected Output: "dcba4321" Click me to see the sample solution.
