strip是删除的意思:split则是分割的意思．strip可以删除字符串的某些字符,split则是根据规定的字符将字符串进行分割． 1.Python strip()函数 介绍 函数原型 声明:s为字符串,rm为要删除的字符序列 s.strip(rm) 删除s字符串中开头.结尾处,位于 rm删除序列 的字符(如果rm中不包含 开头或结尾 的那个字母,则不会删除) s.lstrip(rm) 删除s字符串中开头处,位于 rm删除序列 的字符(如果rm中不包含开头的那个字母,则不会删除) s.rstr

split replace strip是字符串中内置的三个函数,作用分别是分割 替换 去空格 0x01:split split(a,b):用指定的字符(a)分割字符串,可以限制分割的次数(b),返回一个列表 s = '天很1蓝云很1白心1情很1好' ', 2)) 输出结果如下:['天很', '蓝云很', '白心1情很1好'] 但若指定的字符出现在字符串的开头 结尾 或中间连续出现时,列表中会出现空元素,需要对列表进行一个过滤 s = '1天很1蓝云很111白心1情很1好1' result = s

python join 和 split方法的使用,join用来连接字符串,split恰好相反,拆分字符串的. strip()为去除开头结尾指定的字符,空着时是去除空白字符\t,\n,\r意思 1.join用法示例  >>>li = ['my','name','is','bob']  >>>' '.join(li)    #用空格把列表连接起来,所以就成了一个字符串了 'my name is bob'    >>>'_'.join(li)  'my_na

我觉得都可以进行分隔,但最大的不同就是一个返回list,一个返回字符串 s1 = 'deng ye xun' s1.split() Out[8]: ['deng', 'ye', 'xun'] s1.strip() Out[9]: 'deng ye xun'

Python中split()函数,通常用于将字符串切片并转换为列表. 一.函数说明: split():语法: str.split(str="",num=string.count(str))[n] 拆分字符串.通过制定分隔符将字符串进行切片,并返回分割后的字符串列表[list] 参数:str:分隔符,默认为空格,但不能为空("") num: 表示分割次数.如果指定num,则分割成n+1个子字符串,并可将每个字符串赋给新的变量 示例: u = "www.goo

小白,分享记录学习新感悟 路飞的第一次作业写一个登录的程序,作业的升级需求中有个锁文件的需求,大致上如果用户数错了密码三次将用户写到黑名单上,下次登录锁定: ok基本的要求写完,我们上代码 username=['seven','alex'] password=['] print('------welcome--------') count=0 #读入文件 user_lock=[] f=open('aaa_lock','r+') f.seek(0) #光标移动到开头 for line in f.r

先看一个例子: >>> ipaddr = 10.122.19.10 File "", line 1 ipaddr = 10.122.19.10 ^ SyntaxError: invalid syntax >>> ipaddr = "10.122.19.10" >>> ipaddr.strip() '10.122.19.10' >>> ipaddr = '10.122.19.10' >>

  字符串对象方法 split()方法拆分字符串: strip()方法去掉空白符和换行符: split()结合strip()使用: "+"符号可以将多个字符串连接起来: join()方法也是连接字符串,比较它和"+"符号的区别: in关键字判断一个字符串是否包含在另一个字符串中: index()方法和find()方法判断一个子字符串的位置: index()方法和find()方法的区别是:如果不包含子字符串,index()会抛出一个异常,而find()会返回-1. c
