To understand this example, you should have the knowledge of following Python programming topics:
A palindrome is a string which is same read forward or backwards.
For example: "dad" is the same in forward or reverse direction. Another example is "aibohphobia" which literally means, an irritable fear of palindromes.
# Program to check if a string # is palindrome or not # change this value for a different output my_str = 'aIbohPhoBiA' # make it suitable for caseless comparison my_str = my_str.casefold() # reverse the string rev_str = reversed(my_str) # check if the string is equal to its reverse if list(my_str) == list(rev_str): print("It is palindrome") else: print("It is not palindrome")
It is palindrome
Note: To test the program, change the value of my_str in the program.
In this program, we have taken a string stored in my_str.
Using the method
casefold() we make it suitable for caseless comparisons. Basically, this method returns a lowercased version of the string.
We reverse the string using the built-in function
reversed(). Since this function returns a reversed object, we use the
list() function to convert them into a list before comparing.
