40.format(*args, **kwargs).返回一个格式化的S,使用来自args和kwargs的替换。替换用括号('{'和'})标识。
1、as_integer_ratio(self) 获取改值的最简比 1 2 f1=0.75 print(f1.as_integer_ratio()) 其余方法同整型 五、字符串 例如:'hetan'、'liuyao' 每个字符串类的对象都具备以下方法(常用的): 1、capitalize(self)首字母变大写 1 2 name='hetan' print(name.capitalize()) 2、center(self, width, fil...
常用的方法有下面几个,format()方法中 的槽除了包括参数序号,还可以包括格式控制信息。此时,槽的内部样式如下:模板字符串> { : } 格式控制标记> 参数序号> "{" [identifier | integer*]["!" "r" | "s" | "a"] [":" format_spec] "}" ...
"{" [[identifier | integer]("." identifier | "[" integer | index_string "]")*]["!" "r" | "s" | "a"] [":" format_spec] "}" 其中,用来控制参数显示时的格式,包括:,<.精度>6 个字段,这些字段都是可选的,可以组合使用,逐一介绍如下。
