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: ...
python print 不换行(在后面加上,end=''),print(string,end='') Python split()通过指定分隔符对字符串进行切片,如果参数num 有指定值,则仅分隔 num 个子字符串 split()方法语法:str.split(str="", num=string.count(str)). 参数 str -- 分隔符,默认为空格。 num -- 分割次数。 返回值 返回分割后的...

您可以向split()方法传递一个分隔符字符串来指定一个不同的分割字符串。例如,在交互式 Shell 中输入以下内容: >>>'MyABCnameABCisABCSimon'.split('ABC') ['My','name','is','Simon']>>>'My name is Simon'.split('m') ['My na','e is Si','on'] split()的一个常见用法是沿着换行符拆分...

这不是一种可靠的方法来检测何时到达文件末尾。 如您所知,StreamReader.ReadLine()在没有更多行可读时返回null。这应该用来确定你何时到达终点。 您可以将语法缩短为: string line;while ((line = stringReader.ReadLine()) != null){ // line contains the current line here}...
在python 3.x中encode,在转码的同时还会把string变成bytes类型,decode在解码的同时还会把bytes变回string。 20、函数 使用函数的意义: 减少重复的代码 保持一致性,使代码更容易修改 使程序更容易扩展 def 函数名(形参): '''文档描述''' 代码块 return #返回执行结果,可返回多个值,默认返回None #定义一个函数 ...
