Odd and Even using if condition in python

Write a Program to Check Whether a Number is Even or Odd in Python

In this odd and even program, we learn 5 different ways to find the number is odd or even. In the method, we will see to print the odd number and even number, and in some, we will print the boolean value in the place of odd and even number. Even number means True and Odd number means False. We will use the function to find odd and even numbers.

Syntax:

def function_name(parameter):
    statement1
    statement2
    .........

Odd and Even Functions Examples-1 in Python

In this method, we will append method to append the values from the list. We will separate the odd and even numbers.

def odd_even(num):

    odd=[]

    even=[]

    for i in num:

        if i%2 == 0:

            even.append(i)

        else:

            odd.append(i)

    output_num=[odd,even]

    return output_num

number=[1,2,3,12,15,6,7,8,9]

print('Odd Number, Even Number',odd_even(number))

Output:

Odd Number , Even Number [[1, 3, 15, 7, 9], [2, 12, 6, 8]]

Odd and Even Functions Examples-2 in Python

In the second method of printing odd and even numbers, we will take the user input values and then we will print that value as odd or even number. If the number will even then print ‘even’ and if the number will be odd then print ‘odd’. In this method, we are using the if and else statement.

def odd_even(num):
    
    if num%2==0:
        
        return "even"
    
    else:
        
        return 'odd'
    
number = int(input('enter your number: '))

print(odd_even(number))

Output:

C:\Users\Pramod\PycharmProjects\pythonProject\venv\Scripts\python.exe C:/Users/Pramod/PycharmProjects/pythonProject/main.py
enter your number: 3
odd

Odd and Even Functions Examples-3 in Python

In method number 3rd, we will see the same as in method number 2 that we saw but the difference is we are only using if statement not else statement. we are minimizing the code size. 

def odd_even(num):
    
    if num%2==0:
        
        return "even"
    
    return "odd"

numb=int(input("enter any no:"))

print(odd_even(numb))

Output:

print(odd_even(numb))
C:\Users\Pramod\PycharmProjects\pythonProject\venv\Scripts\python.exe C:/Users/Pramod/PycharmProjects/pythonProject/main.py
enter any no:12
even

Process finished with exit code 0

Odd and Even Functions Examples-4 in Python

In method number 4th, we will learn the same as method number 3 but the difference is that we are directly assigning value to the function odd_even and then we are returning True and False.

def odd_even(num):
    
    if num%2==0:
        
        return True
    
    return False

print(odd_even(112))

Output:

C:\Users\Pramod\PycharmProjects\pythonProject\venv\Scripts\python.exe C:/Users/Pramod/PycharmProjects/pythonProject/main.py
True

Process finished with exit code 0

Odd and Even Functions Examples-5 in Python

In method number 4 we say that we are using the if condition to return the True and False statement but in method no. 5 we are returning True and False without any comparison.

def is_even(num):
    
    return num%2==0

numb = int(input('enter any number'))

print(is_even(numb))

C:\Users\Pramod\PycharmProjects\pythonProject\venv\Scripts\python.exe C:/Users/Pramod/PycharmProjects/pythonProject/main.py
enter any number1234
True
