Python – Test for all Even elements in the List for the given Range

When it is required to test all even elements in the list for the given range, a simple iteration and the modulus operator is used.

Below is a demonstration of the same −

Example

 Live Demo

my_list = [32, 12, 42, 61, 58, 60, 19, 16]

print("The list is :")
print(my_list)

i, j = 2, 7

my_result = True
for index in range(i, j + 1):

   if my_list[index] % 2 :
      my_result = False
      break

print("The result is :")

if(my_result == True):
   print("All The elements are in the given range")
else:
   print("All The elements are not in the given range")

Output

The list is :
[32, 12, 42, 61, 58, 60, 19, 16]
The result is :
All The elements are not in the given range

Explanation

• A list is defined and displayed on the console.

• The value for ‘i’ and ‘j’ are defined.

• The value for a variable is set to Boolean ‘True’.

• The list is iterated over, and the modulus operator is used on each element to check if it is even or odd.

• If it is even, the Boolean value is set to ‘False’ and the control breaks out of the loop.

• Based on the Boolean value, relevant message is displayed on the console.
