来个python大神帮解新手解答下

import re
s = 'it is time to meet your destiny'
do_pattern = re.compile(r'\b(m[a-z]{3})\b')
do_result = do_pattern.findall(s)
for i in do_result:
    print(re.search(i,s).start())

word = "it is time to meet youer destiny"
for i in word.split(): # 划分 词组列表
    if i[0] == "m" and len(i) == 4: # 以m 开头且长度为4
        index = word.index(i) # 获取索引
        print(index) # 输出

如果觉得有用，点个采纳，嘿嘿

word. index("meet")
