Python Functions Exercise

Python function is a code block or group of statements that perform a particular task. We use reuse functions whenever required.

This Python functions exercise aims to help Python developers to learn and practice how to create a function, nested functions, and use the function arguments effectively. All questions are tested on Python 3.

This exercise includes the following: –

• It contains 10 questions and solutions provided for each question.
• Coding exercise to solve Python function assignments, programs, questions, and challenges.

This function exercise covers questions on concepts such as function creation, function calls, function arguments, inner functions, built-in functions. Let us know if you have any alternative solutions. It will help other developers.

• Use Online Code Editor to solve exercise questions.
• Read Python functions to solve this exercise

Exercise 1: Create a function that can accept two arguments name and age and print its value

def demo(name, age):
    print(name, age)

demo("Ben", 25)

Exercise 2: Write a function func1() such that it can accept a variable length of  argument and print all arguments value

func1(20, 40, 60)
func1(80, 100)

Expected Output:

func1(20, 40, 60)
20
40
60

func1(80, 100)
80
100

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

func1(20, 40, 60)
func1(80, 100)

Exercise 3: Write a function calculation() such that it can accept two variables and calculate the addition and subtraction of them. And also it must return both addition and subtraction in a single return call

Given:

def calculation(a, b):
    # Your Code

res = calculation(40, 10)
print(res)

Expected Output

50, 30

Expected Output:

def calculation(a, b):
    return a+b, a-b

res = calculation(40, 10)
print(res)

def calculation(a, b):
    return a+b, a-b

add, sub = calculation(40, 10)
print(add)
print(sub)

Exercise 4: Create a function showEmployee() in such a way that it should accept employee name, and its salary and display both. If the salary is missing in the function call assign default value 9000 to salary

Given:

showEmployee("Ben", 9000)
showEmployee("Ben")

Expected output:

Employee Ben salary is: 9000
Employee Ben salary is: 9000

def showEmployee(name, salary=9000):
    print("Employee", name, "salary is:", salary)

showEmployee("Ben", 9000)
showEmployee("Ben")

Exercise 5: Create an inner function to calculate the addition in the following way

• Create an outer function that will accept two parameters, a and b
• Create an inner function inside an outer function that will calculate the addition of a and b
• At last, an outer function will add 5 into addition and return it

def outerFun(a, b):
    square = a**2
    def innerFun(a,b):
        return a+b
    add = innerFun(a, b)
    return add+5

result = outerFun(5, 10)
print(result)

Exercise 6: Write a recursive function to calculate the sum of numbers from 0 to 10

Expected Output:

55

def calculateSum(num):
    if num:
        return num + calculateSum(num-1)
    else:
        return 0

res = calculateSum(10)
print(res)

Exercise 7: Assign a different name to function and call it through the new name

Below is the function displayStudent(name, age). Assign a new name showStudent(name, age) to it and call through the new name

def displayStudent(name, age):
    print(name, age)

displayStudent("Emma", 26)

You should be able to call the same function using

showStudent(name, age)

def displayStudent(name, age):
    print(name, age)

displayStudent("Emma", 26)

showStudent = displayStudent
showStudent("Emma", 26)

Exercise 8: Generate a Python list of all the even numbers between 4 to 30

Expected Output:

[4, 6, 8, 10, 12, 14, 16, 18, 20, 22, 24, 26, 28]

print(list( range(4, 30, 2)))

Exercise 9: Return the largest item from the given list

aList = [4, 6, 8, 24, 12, 2]

Expected Output:

24

aList = [4, 6, 8, 24, 12, 2]
print(max(aList))
