palindrome string in python code example

Example 1: string palindrome in python

n = input("Enter the word and see if it is palindrome: ") #check palindrome
if n == n[::-1]:
    print("This word is palindrome")
else:
    print("This word is not palindrome")

Example 2: Write a function that tests whether a string is a palindrome

def palindrome_check(string):
    string = list(string)
    tmp = []
    #remove any spaces
    for x in range(0, len(string)):
        if(string[x] != " "):
            tmp.append(string[x].lower())
    
            
    #now reverse the string
    array1 = []
    i = 0
    j = len(tmp)-1

    while(i < len(tmp)):
        array1.append(tmp[j])
        i += 1
        j -= 1

    #check if array1 is equal to the string
    counter = 0
    for x in range(0, len(tmp)):
        if(tmp[x] == array1[x]):
            counter += 1

    #if the counter is equal to the length of the string then the word
    #is the same
    if(counter == len(tmp)):
        return True
    
    return False

Example 3: 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 4: 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")
