number palindrome triangle in python code example

Example 1: palindrome python

#A palindrome is a word, number, phrase, or other sequence of characters which reads the same backward as forward.
#Ex: madam or racecar.
def is_palindrome(w):
	if w==w[::-1]: # w[::-1] it will reverse the given string value.
		print("Given String is palindrome")
	else:
		print("Given String is not palindrome")

is_palindrome("racecar")

Example 2: palindrome without using string function in python

n = input("eNTER  STRING\n")
length = int(len(n))
n = str(n)

for i in range(0, int(length/2+1)):
   if n[i] != n[-i - 1]:
      break

if i < int(length/2 + 1):
   print("not")
else:
   print("yes")
