Python – Test if list is Palindrome
When it is required to test if a list is a palindrome, a method is defined that reverses the string and checks if it is equal to the original string. Based on the result, relevant message is displayed on the console. A list comprehension and the ‘join’ method are used.
Example
Below is a demonstration of the same
def check_palindrome_list(my_str):
if my_str == my_str[::-1]:
print("The list is a palindrome")
else:
print("The list isn't a palindrome")
my_list = [77, 1, 56, 65, 1, 77]
print("The list is :")
print(my_list)
my_list = ' '.join([str(elem) for elem in my_list])
check_palindrome_list(my_list)Output
The list is : [77, 1, 56, 65, 1, 77] The list is a palindrome
Explanation
A method named ‘check_palindrome_list’ is defined that takes a string as a parameter.
The string is reversed and it is compared to the original string.
Based on the result, relevant message is displayed on the console.
Outside the method, a list is defined and is displayed on the console.
It is iterated over and the ‘join’ method is used to join the elements and converted to a string.
The method is called by passing the required parameter.
The output is displayed on the console.
