#Do you know what a palindrome is?

#It's a word which look the same when read forward and backward. For example, "kayak" is a palindrome, while "loyal" is not.

#Your task is to write a program which:

#asks the user for some text;
##Note: assume that an empty string isn't a palindrome;
#treat upper- and lower-case letters as equal;
#spaces are not taken into account during the check - treat them as non-existent;
#there are more than a few correct solutions - try to find more than one.
#Test your code using the data we've provided.

#Test data
#Sample input:

#Ten animals I slam in a net

#Sample output:

#It's a palindrome


#Sample input:

#Eleven animals I slam in a net

#Sample output:

#It's not a palindrome


checkpali = input("Please enter a phrase to check: \n")
#strip all irrelevant characters and spaces
#convert all characters to lower case
checkpali = checkpali.lower()
#print(checkpali)
palifiltered = ''
for letter in checkpali:
    if letter.isalpha():
        palifiltered += letter

#print(palifiltered)

ispalindrome = True
for space in range(int(len(palifiltered)/2)):
    if palifiltered[space]==palifiltered[-(space+1)]:
        continue
    else:
        ispalindrome = False
        break

#print(ispalindrome)
if ispalindrome == True:
    print("It's a palindrome")
elif ispalindrome == False:
    print("It's not a palindrome")
