format用法 相对基本格式化输出采用'%’的方法,format()功能更强大,该函数把字符串当成一个模板,通过传入的参数进行格式化,并且使用大括号'{}’作为特殊字符代替'%’ 使用方法由两种:b.format(a)和format(a,b)。 1、基本用法 (1)不带编号,即“{}” ...

int(x, base=10)base是进制,默认是十进制 int函数常用来将其他类型的数据转换成整型 注意: x 有两种:str / int 1、若 x 为纯数字,就不能给base传参数,否则就会报错 2、若 x 为 str,则可以给base传参,不传就默认是10;给base传什么参数就认为此字符串为什么进制的数,然后把它转换成十进制的数,但字符...
