How to check if the length of a string is equal to the number appended at its end in Python

Answer 1

def is_length_equal_to_appended_number(s):
    num = 0
    i = len(s) - 1
    
    # Traverse the string from the end to extract the number
    while i >= 0 and s[i].isdigit():
        num = num + int(s[i]) * (10 ** (len(s) - 1 - i))
        i -= 1
    
    # Compare the length of the string (excluding the number) with the extracted number
    return len(s[:i+1]) == num


s = "python programming18"

print(is_length_equal_to_appended_number(s))
