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:keyandrev
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。

In Python, you can sort iterables with the sorted() built-in function. To get started, you’ll work with iterables that contain only one data type.Remove ads Sorting NumbersYou can use sorted() to sort a list in Python. In this example, a list of integers is defined, and then ...
Python3.7.5 Windows7环境 方法/步骤 1 先来查看sort方法。这里顺便说一个sorted函数。可以看到list.sort是一个method，而不是函数。而sorted是一个built-in function内置函数，可以对列表、元组、字符串等排序。2 首先要明确sort仅对list做排序，sort是list的一个方法。格式化并赋值给b以后，才能使用sort操作。3 ...
