S.split(sep=None, maxsplit=-1) -> list of strings Return a list of the words in S, using sep as the delimiter string. If maxsplit is given, at most maxsplit splits are done. If sep is not specified or is None, any whitespace string is a separator and empty strings are removed ...
通过指定分隔符sep对字符串进行分割,并返回分割后的字符串列表,类似于split()函数,只不过 rsplit()函数是从字符串右边(末尾)开始分割。 语法:str.rsplit(sep=None, maxsplit=-1) -> list of strings 返回 字符串列表 或str.rsplit(sep=None, maxsplit=-1)[n] 参数: sep —— 分隔符,默认为空格,但不...

返回一个以sep作为分隔符得到的列表。maxsplit代表分隔几次,默认为全分隔17、S.rsplit(sep=None, maxsplit=-1) ->list of strings 同上。不过是从右至左18、S.splitlines([keepends]) ->list of strings 返回一个按换行符作为分隔符得到的列表。默认keepends为False,表示得到的列表,列表的元素都去掉了换行符...
split(sep=None,maxsplit=-1)->list of strings 1. 从左至右 sep指定分割字符串,缺省的情况下空白字符串作为分隔符 maxsplit 指定分割的次数,-1表示遍历整个字符串 将字符串按照分隔符分割成若干字符串,并立即返回列表 'x y'.sp;it() # 至少一个空白字符,如果连续,人做一个,一刀两断 ...
list_example = [1, 2, 2, 3, 3, 3] print(set(list_example)) # {1, 2, 3} str_example = "banana" print(set(str_example)) # {'a', 'b', 'n'} dict() - 创建字典 dict() 函数可以从键值对序列创建字典。 list_of_tuples = [("name", "Alice"), ("age", 25)] print(dict...
str.rsplit(sep=None,maxsplit=-1) -> list of strings从右往左切割 sep指定分割字符串,缺省的情况下空白字符串作为分隔符 maxsplit指定分割次数,-1表示遍历整个字符串(默认是-1)实例(Python3.0+):1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 s1 = "i'm \ta super student" print(s1.r...
Python 複製 temperatures = "Daylight: 260 F\n Nighttime: -280 F" temperatures_list = temperatures.split('\n') print(temperatures_list) 輸出:['Daylight: 260 F', 'Nighttime: -280 F']當您需要迴圈來處理或擷取資訊時,或是從文字檔或其他資源載入資料時,這種分割方式就很方便。
Python 3.5’s type hinting provides an answer for this. Namely, you can express the hint as “a list of strings”: from typing import List def greeting(names: List[str]) -> str: return 'Hello, {}'.format(', '.join(names))
