palindrome program 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: python palindrome
def palindrome(a):
return a == a[::-1]
palindrome('radar') # True
Example 3: 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 4: palindrome number + python
number=int(input("Enter any number :"))
#store a copy of this number
temp=number
#calculate reverse of this number
reverse_num=0
while(number>0):
#extract last digit of this number
digit=number%10
#append this digit in reveresed number
reverse_num=reverse_num*10+digit
#floor divide the number leave out the last digit from number
number=number
#compare reverse to original number
if(temp==reverse_num):
print("The number is palindrome!")
else:
print("Not a palindrome!")
Example 5: 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 6: palindrome words python
mes=input("Enter the word and see if it is palindrome ")
if mes==mes[::-1]:
print("This word is palindrome")
else:
print("This word is not palindrome")
