 python function problems for practice pdf   

problem 1

Define a function that accepts 2 values and return its sum, subtraction and multiplication.                                                    

Hint
Input:
Enter value of a = 7
Enter value of b = 5

Expected output 
Sum is = 12
Sub is = 2
Multiplication is = 35

solution

def result(a, b):
    sum = a+b
    sub = a-b
    mul = a*b
    print(f"Sum is {sum}, Sub is {sub}, & Multiply is {mul}")

a = int(input("Enter value of a: "))  # 7
b = int(input("Enter value of b: "))  # 5
result(a,b)

problem 2

Define a function that accepts  roll number and returns whether the student is present or absent.

Hint
Use a list to store sample roll. no.
Get input from a user and check if the number
exist in the list or not, if exists return present
else return absent

solution

def detail(roll):
    x = [23,43,22,56]
    if roll in x:
        print(f"Roll number {roll} is present")
    else:
        print(f"Roll number {roll} is absent")
roll = int(input("Enter roll no. ")) # 24
detail(roll)

# output
# Roll number 24 is absent

problem 3

Define a function in python that accepts 3 values and returns the maximum of three numbers.

Hint
Input:
Value of a = 30
Value of b = 22
value of c = 18

Expected output 
30 is the maximum among all

solution

def max(a, b, c):
    if a > b and a > c:
        print(f"{a} is maximum among all")
    elif b > a and b > c:
        print(f"{b} is maximum among all")
    else:
        print(f"{c} is maximum among all")

max(30,22,18)

problem 4

Define a function that accepts a number and returns whether the number is even or odd      .

Hint
Input:
Enter a number = 4

Expected output 
4 is an even number

Hint
Input:
Enter a number = 5

Expected output 
4 is an odd number

solution

def func(x):
    if x % 2 == 0:
        print(f"{x} is Even number")
    else:
        print(f"{x} is Odd number")
x = int(input("Enter a number "))
func(4)

problem 5

Define a function which counts vowels and consonant in a word.

Hint
Input:
Enter a word = pythonlobby

Expected output 
Count of vowel is = 2
Count of consonant is = 9

solution

def count(val):
    vov = 0
    con = 0
    for i in range(len(val)):
        if val[i] in ['a','e','i','o','u']:
            vov = vov+1
        else:
            con = con + 1

    print("Count of vowels is ",vov)
    print("Count of consonant is ",con)

x = input("Enter Value: ") # pythonlobby
count(x)

problem 6

Define a function that returns Factorial of a number.

Hint
Input:
Enter a number = 6

Expected output 
Factorial is 720

solution

def factorial(num):
    fact = 1
    while(num!=0):
        fact *= num
        num = num - 1
    print("Factorial is",fact)

num = int(input("Enter number "))
factorial(num)

problem 7

Define a function that accepts lowercase words and returns uppercase words.

Hint
Input:
Enter a word = pythonlobby

Expected output 
Result is = PYTHONLOBBY

solution

def response(text):
    z = text.upper()
    print(z)

text = input("Enter String: ")  # pythonlobby
response(text)

problem 8

Hint
Input:
Enter radius  4

Expected output 
Area of a circle is  50.24

solution

def area(radius):
    area = 3.14*radius*radius
    return area

radius = int(input("Enter Radius: "))  # 4
print(area(radius))
