Program to get the factorial of a given number

by

In this python function program, we will create a function to get the factorial of a given number. A factorial is a mathematical operation that you write like this: n! . It represents the multiplication of all numbers between 1 and n.

What is Function?
It is a block of code that executes when it is called.
To create a function use def keyword.

Steps to solve the program
  1. Create a function fact.
  2. Use the def keyword to define the function.
  3. Pass a parameter i.e. number to the function.
  4. Create a variable named fact and assign its value equal to 1.
  5. While the input number is greater than 0 multiply the fact by the number.
  6. After each multiplication subtract 1 from the input number.
  7. Print the output.
  8. Pass the number to the function while calling the function.
				
					def fact(n):
    fact = 1
    while n > 0:
        fact *= n
        n -= 1
    print(f"Factorial of {num}: {fact}")
num = int(input("Enter a number: "))
fact(num)

Output :

				
					Enter a number: 5
Factorial of 5: 120

Program to create a function with *args as parameters

by

In this python function program, we will create a function with *args as parameters. 

What is *args?
*args allows us to pass a variable number of non-keyword arguments to a Python function.

What is Function?
It is a block of code that executes when it is called.
To create a function use def keyword.

Steps to solve the program
  1. Create a function func
  2. Use the def keyword to define the function.
  3. Pass multiple parameters to the function using *args.
    *args is used to pass multiple objects to the function.
  4. Use a for loop to iterate numbers and print the cube of each number.
  5. Pass multiple numbers to the function while calling the function.
				
					def func(*args):
    for num in args:
        print(num**3,end=" ")
func(5,6,8,7)

Output :

				
					125 216 512 343

Python function program to find the HCF of two numbers

by

In this python function program, we will find the HCF of two numbers.

HCF:
HCF stands for Highest Common Factor. HCF of two or more numbers is the greatest factor that divides the numbers.

What is Function?
It is a block of code that executes when it is called.
To create a function use def keyword.

Steps to solve the program
  1. Create a function hcf.
  2. Use the def keyword to define the function.
  3. Pass two parameters i.e. numbers to the function.
  4. Using an if-else statement check which number is smaller.
  5. Use for loop with the range function to iterate over numbers from 1 to the smaller number.
  6. During iteration check whether the iterated number divides both input numbers, if yes then assign that number to the variable.
  7. After the loop is finished print the output.
  8. Take two numbers as input through the user and pass them to the function while calling the function.
				
					def hcf(num1,num2):
    if num1 > num2:
        smaller = num2
    else:
        smaller = num1

    for i in range(1, smaller+1):
        if((num1 % i == 0) and (num2 % i == 0)):
            hcf = i

    print(f"H.C.F of {num1} and {num2}: {hcf}")
    
num1 = int(input("Enter number 1: "))
num2 = int(input("Enter number 2: "))
hcf(num1,num2)

Output :

				
					Enter number 1: 24
Enter number 2: 54
H.C.F of 24 and 54: 6

Python function program to find the LCM of two numbers

by

In this python function program, we will find the LCM of two numbers.

LCM:
LCM stands for ‘Least Common Multiple’ or the Lowest Common Multiple. The least common multiple (LCM) of two numbers is the lowest possible number that can be divisible by both numbers.

What is Function?
It is a block of code that executes when it is called.
To create a function use def keyword.

Steps to solve the program
  1. Create a function lcm
  2. Use the def keyword to define the function.
  3. Pass two parameter i.e. numbers to the function.
  4. Using an if-else statement check which number is greater.
  5. Use While loop.
  6. Inside the While loop check whether both numbers divide the greater number or not.
  7. If yes then break the loop otherwise, add 1 to the greater number and let the loop continue.
  8. At the end print the output.
  9. Take two numbers as input through the user and pass them to the function while calling the function.
				
					def lcm(num1,num2):
    if num1 > num2:
        greater = num1
    else:
        greater = num2

    while(True):
        if((greater % num1 == 0) and (greater % num2 == 0)):
            lcm = greater
            break
        greater += 1

    print(f"L.C.M of {num1} and {num2}: {lcm}")

num1 = int(input("Enter number 1: "))
num2 = int(input("Enter number 2: "))   
lcm(num1,num2)

Output :

				
					Enter number 1: 12
Enter number 2: 20
L.C.M of 12 and 20: 60
