如何从用户提供的字符串中找到所有计数连续的字母？

def find_consecutive_letters(string):
    consecutive_sequences = []
    temp_sequence = ""

    for i in range(len(string)):
        if string[i].isalpha():
            if i < len(string) - 1 and ord(string[i+1]) - ord(string[i]) == 1:
                temp_sequence += string[i]
            else:
                if len(temp_sequence) >= 2:
                    consecutive_sequences.append(temp_sequence + string[i])
                temp_sequence = ""

    if len(temp_sequence) >= 2:
        consecutive_sequences.append(temp_sequence)

    return consecutive_sequences
