string.split(str="", num=string.count(str)) 以str 为分隔符切片 string,如果 num 有指定值,则仅分隔 num+ 个子字符串 string.splitlines([keepends]) 按照行('\r', '\r\n', \n')分隔,返回一个包含各行作为元素的列表,如果参数 keepends 为 False,不包含换行符,如果为 True,则保留换行符。 string...
示例1:演示split()函数如何工作的例子 text = 'geeks for geeks' # Splits at space print(text.split()) word = 'geeks, for, geeks' # Splits at ',' print(word.split(',')) word = 'geeks:for:geeks' # Splitting at ':' print(word.split(':')) ...
def split(s): i = 0 ans = [] while i < len(s): start = i # find space while i < len(s) and s[i] != ' ': i += 1 ans.append(s[start:i]) i += 1 if s and s[-1] == " ": ans.append("") return ans
