How to make this for loop in Python work?

Question

I want to spit out a list of palindromes until a certain letter I give.

It\'s about this part:

def pyramid_palindrome(last_letter):
    for letter in         


        

Answer 1

Your problem was when calling your two palindrome functions and on how you were changing the value for last_letter-

I tried to modify your code as little as possible:

def pyramid_palindrome(last_letter):
    for letter in range(97,last_letter):
        print(call_first_part_palindrome(letter) + call_second_part_palindrome(letter-2))

And this remains the same:

def call_first_part_palindrome(last_letter):

    letters_a_to_y = ""             

    for letter in range(97,last_letter):
        letters_a_to_y += chr(letter) 

    return(letters_a_to_y)

def call_second_part_palindrome(last_letter): 

    letters_y_to_a = ""

    for letter in range(last_letter,96,-1): 
        letters_y_to_a += chr(letter)

    return(letters_y_to_a)

pyramid_palindrome(112)

Which outputs:

a
aba
abcba
abcdcba
abcdedcba
abcdefedcba
abcdefgfedcba
abcdefghgfedcba
abcdefghihgfedcba
abcdefghijihgfedcba
abcdefghijkjihgfedcba
abcdefghijklkjihgfedcba
abcdefghijklmlkjihgfedcba
abcdefghijklmnmlkjihgfedcba
