Palandrome Checking with Python

[scottalanmiller]

I provided one example on how to check a palandrome with Python using recursion. Here is a longer and more traditional example without using recursion. There is some extra print statements to show where the logic is being hit as it runs.

pal = input("Enter the palandrome to verify: ")

print("Your palandrome is: ", pal)

palLength = len(pal)

frontIndex = 0
backIndex  = palLength - 1

while True:
    if frontIndex == backIndex:
        print("It is an " + pal[frontIndex] + " so far so good.")
        print("Success.")
        break
    if pal[frontIndex] == pal[backIndex]:
        print("It is an " + pal[frontIndex] + " so far so good.")
    else:
        print("Fail.")
        break
    if frontIndex == (backIndex - 1):
        print("It's good.")
        break
    else:
        frontIndex += 1
        backIndex -= 1
