re.finditer(pattern, string, flags=0) 与findall差不多,不一样的地方是:返回一个包含匹配对象的迭代器 示例 for ans in re.finditer(r'\w+', 'Words, words, words.'): print(ans.group(), end='\t') # out: Words words words for ans in re.finditer(r'\w+', 'Words, words, words.'...

A string is good if it can be formed by characters from chars (each character can only be used once). Return the sum of lengths of all good strings in words. Example 1: Input: words = ["cat","bt","hat","tree"], chars = "atach" Output: 6 Explanation: The strings that can be...
import rewords = "I am learning Pythonnnnnn, that 's awesome!"result = re.findall('[a-zA-Z]{1,11}', words)print(result)>>> ['I', 'am', 'learning', 'Pythonnnnnn', 'that', 's', 'awesome'] 1. {最短匹配长度,最长匹配长度},在配合上字符集的正则写法,既可拆分出原有的单词,注...
s='There are 12 cats and 3 dogs in the house.'words=re.findall('[a-z]+',s)print(words) Python Copy 运行结果为: ['here','cats','and','dogs','in','the','house'] Bash Copy 正则表达式[a-z]+用于匹配一个或多个小写字母。re.findall()函数返回一个列表,其中包含找到的所有单词。
