以Python 3.60 版本为例,一共存在 68 个这样的函数,它们被统称为 内建函数(Built-in Functions)。 之所以被称为内建函数,并不是因为还有“外建函数”这个概念,“内建”的意思是在 Python 3.60 版本安装完成后,你无须创建就可以直接使用这些函数,即 表示这些函数是“自带”的而已。 Python 3.60 的 68个 内建...

另外,Python的字符串支持序列类型中描述的序列类型方法 - str,unicode,list,tuple,bytearray,buffer,xrange部分。要输出格式化的字符串,请使用%字符串格式操作部分中描述的模板字符串或运算符。另请参阅re模块,了解基于正则表达式的字符串函数。 str.capitalize() ...
