Python has two basic function for sorting lists:sortandsorted. Thesortsorts the list in place, while thesortedreturns a new sorted list from the items in iterable. Both functions have the same options:keyandreverse. Thekeytakes a function which will be used on each value in the list being ...

如:列表的 sort 方法,调用时就是 list.sort()。 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。
