Python – Check if elements in a specific index are equal for list elements

Python Server Side Programming Programming

When it is required to check if the elements in a specific index are equal to another list of elements, a simple iteration and a Boolean value are used.

Example

Below is a demonstration of the same −

my_list_1 = [69, 96, 23, 57, 13, 75, 13]
my_list_2 = [68, 21, 69, 23, 49, 35, 73]

print("The first list is : " )
print(my_list_1)

print("The first list after sorting is :")
my_list_1.sort()
print(my_list_1)

print("The second list is : " )
print(my_list_2)

print("The first list after sorting is :")
my_list_2.sort()
print(my_list_2)

check_list = [66, 89, 69]
print("The second list is : " )
print(check_list)

print("The check list after sorting is :")
check_list.sort()
print(check_list)

my_result = True
for index, element in enumerate(my_list_1):

   if my_list_1[index] != my_list_2[index] and element in check_list:
      my_result = False
      break

if(my_result == True):
   print("The elements of the list are equal to the elements in the check list")
else:
   print("The elements of the list aren't equal to elements in the check list")

Output

The first list is :
[69, 96, 23, 57, 13, 75, 13]
The first list after sorting is :
[13, 13, 23, 57, 69, 75, 96]
The second list is :
[68, 21, 69, 23, 49, 35, 73]
The first list after sorting is :
[21, 23, 35, 49, 68, 69, 73]
The second list is :
[66, 89, 69]
The check list after sorting is :
[66, 69, 89]
The elements of the list aren't equal to elements in the check list

Explanation

Two lists of integers are defined and are displayed on the console.
They are sorted and displayed on the console.
A Boolean value is assigned to True.
The first list is iterated over using ‘enumerate’.
The elements at specific indices are compared and the element is checked to be found in the third list.
If it is not found, the Boolean value is assigned to ‘False’.
The control breaks out of the loop.
Depending on the Boolean value, the message is displayed on the console.
