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 ...
以string作为分隔符,将seq中所有的元素(的字符串表示)合并为一个新的字符串。 list_of_strings = ['string', 'methods', 'in', 'python'] s = '-'.join(list_of_strings) print(s) # string-methods-in-python list_of_strings = ['string', 'methods', 'in', 'python'] s = ' '.join(lis...
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...
文字序列类型(text sequence type):字符串数据类型 序列类型(sequence type):list tuple 映射类型(mapping type):dict 集合类型(set type) : set 数字number 整型int 整数类型有4种进制表示:十进制、二进制(0b)、八进制(0o)和十六进制(0x)。 浮点型float Python语言中要求浮点数类型必须带有小数部分,小数部分可...

2.string转list 命令:list(str) import string str = 'abcde' print(str) #输出:abcde list1 = list(str) print(list1) #输出:['a', 'b', 'c', 'd', 'e'] 这里在jupyter报错,在pycharm上没有出错,网上说是命名成list问题,但改过也如此。母鸡了!

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))
rsplit(sep=None, maxsplit=-1) -> list of strings maxsplit表示最大切割数,r表示反向切割 从右向左 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 s1 = "T'm \ta super student." s1.rsplit() ...
