Python Basic: Exercise-21 with Solution

Write a Python program to find whether a given number (accept from the user) is even or odd, print out an appropriate message to the user.

Is named even in python?

Sample Solution:-

Python Code:

num = int(input("Enter a number: "))
mod = num % 2
if mod > 0:
    print("This is an odd number.")
else:
    print("This is an even number.")	

Sample Output:

Enter a number: 5                                                                                             
This is an odd number.

Python: Tips of the Day

Concatenating iterable to a single string:

>>> x = ["python","really", "rocks"]
>>> " ".join(x)
'python really rocks'

A number is even if it is perfectly divisible by 2. When the number is divided by 2, we use the remainder operator % to compute the remainder. If the remainder is not zero, the number is odd.

Source Code

# Python program to check if the input number is odd or even.
# A number is even if division by 2 gives a remainder of 0.
# If the remainder is 1, it is an odd number.

num = int(input("Enter a number: "))
if (num % 2) == 0:
   print("{0} is Even".format(num))
else:
   print("{0} is Odd".format(num))

Output 1

Enter a number: 43
43 is Odd

Output 2

Enter a number: 18
18 is Even

In this program, we ask the user for the input and check if the number is odd or even. Please note that { } is a replacement field for num.

Python Program to Check if a Number is Odd or Even

Odd and Even numbers:

If you divide a number by 2 and it gives a remainder of 0 then it is known as even number, otherwise an odd number.

Even number examples: 2, 4, 6, 8, 10, etc.

Odd number examples:1, 3, 5, 7, 9 etc.

Given a list of numbers, write a Python program to print all even numbers in the given list.

Example: 

Input: list1 = [2, 7, 5, 64, 14]
Output: [2, 64, 14]
Input: list2 = [12, 14, 95, 3]
Output: [12, 14]

Method 1: Using for loop

Iterate each element in the list using for loop and check if num % 2 == 0. If the condition satisfies, then only print the number. 

Python3

list1 = [10, 21, 4, 45, 66, 93]

for num in list1:

    if num % 2 == 0:

        print(num, end=" ")

Output: 

10, 4, 66

Method 2: Using while loop 

Python3

list1 = [10, 24, 4, 45, 66, 93]

num = 0

while(num < len(list1)):

    if list1[num] % 2 == 0:

        print(list1[num], end=" ")

    num += 1

Output: 

10, 4, 66

Method 3: Using list comprehension 

Python3

list1 = [10, 21, 4, 45, 66, 93]

even_nos = [num for num in list1 if num % 2 == 0]

print("Even numbers in the list: ", even_nos)

Output: 

Even numbers in the list:  [10, 4, 66]

Method 4: Using lambda expressions 

Python3

list1 = [10, 21, 4, 45, 66, 93, 11]

even_nos = list(filter(lambda x: (x % 2 == 0), list1))

print("Even numbers in the list: ", even_nos)

Output

Even numbers in the list:  [10, 4, 66]

Method 5: Using Recursion

Python3

def evennumbers(list, n=0):

    if n==len(list):

        exit()

    if list[n]%2==0:

        print(list[n], end=" ")

    evennumbers(list, n+1)

list1 = [10, 21, 4, 45, 66, 93]

print("Even numbers in the list:", end=" ")

evennumbers(list1)

Output

Even numbers in the list: 10 4 66 

Method: Using enumerate function 

Python3

list1 = [2, 7, 5, 64, 14]

for a,i in enumerate(list1):

  if i%2==0:

    print(i,end=" ")

Method: Using pass 

Python3

list1 = [2, 7, 5, 64, 14]

for i in list1:

  if i%2!=0:

    pass

  else:

    print(i,end=" ")

Auxiliary Space: O(1)

Method: Using numpy.array

Python3

import numpy as np

temp = [2, 7, 5, 64, 14]

li = np.array(temp)

even_num = li[li % 2 == 0]

print(even_num)

Output:

[ 2 64 14]

Is named even Python?

Python Code: num = int(input("Enter a number: ")) mod = num % 2 if mod > 0: print("This is an odd number. ") else: print("This is an even number. ")

How do you check if a value is even in Python?

The required code is provided below. num = int (input (“Enter any number to test whether it is odd or even: “) if (num % 2) == 0: print (“The number is even”) else: print (“The provided number is odd”) Output: Enter any number to test whether it is odd or even: 887 887 is odd.

What == means in Python?

The == operator compares the value or equality of two objects, whereas the Python is operator checks whether two variables point to the same object in memory. In the vast majority of cases, this means you should use the equality operators == and != , except when you're comparing to None .

How do you check if a number is even?

If a number is evenly divisible by 2 with no remainder, then it is even. You can calculate the remainder with the modulo operator % like this num % 2 == 0 . If a number divided by 2 leaves a remainder of 1, then the number is odd.
