Solution

Sure, here is a step-by-step guide on how to write a Python program to count the number of palindrome strings in a given string.

Step 1: Define a function to check if a string is a palindrome.

def is_palindrome(s):
    return s == s[::-1]

This function takes a string s as input and returns True if s is a palindrome and False otherwise. The [::-1] slice reverses the string.

Step 2: Define a function to count the number of palindrome substrings in a string.

def count_palindromes(s):
    count = 0
    for i in range(len(s)):
        for j in range(i + 1, len(s) + 1):
            if is_palindrome(s[i:j]):
                count += 1
    return count

This function takes a string s as input and returns the number of palindrome substrings in s. It uses a nested loop to generate all possible substrings of s and checks each one to see if it's a palindrome.

Step 3: Test the function with some input.

print(count_palindromes('madam'))  # Output: 7

This will count the number of palindrome substrings in the string 'madam', which are 'm', 'a', 'd', 'a', 'm', 'ada', 'madam'. So, the output is 7.

Please note that this program counts single characters as palindromes. If you want to count only palindromes of length 2 or more, you can modify the is_palindrome function to return False for strings of length less than 2.
