Lastly, an important application of strings is thesplitmethod, which returns a list of all the words in the initial string and it automatically splits by any white space. It can optionally take a parameter and split the strings by another character, like a comma or a dot 4. Formatting str...
rindex( str, beg=0, end=len(string))类似于 index(),不过是从右边开始. 29 rjust(width,[, fillchar])返回一个原字符串右对齐,并使用fillchar(默认空格)填充至长度 width 的新字符串 30 rstrip()删除字符串末尾的空格或指定字符。 31 split(str="", num=string.count(str)) 以str 为分隔符截取字符...

抱歉,field_names不像一个str那样嘎嘎叫:它没有.replace,或者返回我们无法.split的东西。④如果引发了AttributeError,那么field_names不是一个str,我们假设它已经是一个名称的可迭代对象。⑤为了确保它是可迭代的并保留我们自己的副本,将我们拥有的内容创建为一个元组。tuple比list更紧凑,还可以防止我的代码误改名称...
There.split()function takes a regular expression pattern as its first argument and the target string as its second argument. You can use this function to split strings based on complex criteria, such as multiple, inconsistently used delimiters: ...

这里我们先将'192.168.1.0'赋值给floor1这个变量,再对该变量调用split()这个方法,然后将返回的值赋值给另外一个变量floor1_list,注意这里split()括号里的'.'表示分隔符,该分隔符用来对字符串进行切片,因为IP地址的写法都是4个数字用3个点'.'分开,所以这里分隔符用的是'.',因为split()返回的值是列表,所以这里...
