Python里sorted函数,定义如下: Definition:sorted(iterable:Iterable[SupportsLessThanT],/,*,key:None=...,reverse:bool=...)->List[SupportsLessThanT]Returnanewlistcontainingallitemsfromtheiterableinascendingorder.Acustomke
keyOptional. A Function to execute to decide the order. Default is None reverseOptional. A Boolean. False will sort ascending, True will sort descending. Default is False More Examples Example Sort numeric: a = (1,11,2) x =sorted(a) ...
函数(Function):是通过 funcname() 直接调用。 如内置函数(built-in function) sorted,调用时就是 sorted()。 注:Python API 的一个惯例(convention)是:如果一个函数或者方法是原地改变对象,那么应该返回 None。这么做的目的是为了告诉调用者对象被原地改变了。这个约定的弊端是无法级联调用(cascade call)这些方法...
