Program to display even and odd numbers without if

program to display even and odd numbers without if

In this program, we will discuss the concept of program to display even and odd numbers without if statement in Python

In this post, we are going to learn how to display even and odd numbers without using if statement in Python programming language.

 

First, we must understand how to identify even and odd numbers

What is Even or Odd

When the number is divided by 2 and the balance becomes zero and the above number is called as the even number – eg 2,4,6,8,10

and on the other sides when it is divided by 2 and balance becomes 1 they are called odd numbers or uneven numbers

eg- 1, 3, 5, 7, 9

In my previous post, I have explained the various approaches to display  even or odd numbers using if statements in Python language

 

here, we will discuss how to display odd and even numbers without if statements in Python programming language

 

There are four programs given below

Print even  numbers  using for loop in Python

Program 1

The program allows the user to enter the maximum number for display all even numbers using for loop in Python

It will display the even  numbers without using if statements.

#print even number using Python for loop
num=int(input("Enter the maximum: "))
for i in range(2,num,2):
     print (i),

When the above code is executed, it produces the following results

Enter the maximum: 30 
2 4 6 8 10 12 14 16 18 20 22 24 26 28

 

Print odd numbers  using for loop in Python

Program 2

The program allows the user to enter the maximum number for display all odd  numbers

It will display the  odd numbers without using if statements.

 

#print even number using Python for loop
num=int(input("Enter the maximum: "))
for i in range(1,num,2):
     print (i),

When the above code is executed, it produces the following results

Enter the maximum: 30 
1 3 5 7 9 11 13 15 17 19 21 23 25 27 29

 

Program 3

Print even numbers using while loop in Python

The program allows the user to enter the maximum number for display all even numbers using while loop in Python

Then, it will display the even and odd numbers without using if statements.

#print even number using Python for loop
num=int(input("Enter the maximum: "))
i=2
while i<=num:
    print (i),
    i=i+2

When the above code is executed, it produces the following results

Enter the maximum: 26
2 4 6 8 10 12 14 16 18 20 22 24 26

Program 4

Print odd numbers using while loop in Python

The program allows the user to enter the maximum number for display all odd  numbers

Then, it will display the even and odd numbers without using if statements in Python language

Program 2

#print even number using Python for loop
num=int(input("Enter the maximum: "))
i=1
while i<=num:
    print (i),
    i=i+2

When the above code is executed, it produces the following results

Enter the maximum: 40
1 3 5 7 9 11 13 15 17 19 21 23 25 27 29 31 33 35 37 39
