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 使用sort将会生成一个新的列...
Python List sort() method sorts the list elements in the natural ordering. The sorting happens in-place, so the list is modified. Python List sort()方法以自然顺序对列表元素进行排序。 排序发生在原位,因此列表被修改。 Python has a built-in function –sorted()– which is used to create a so...
其中,data是待排序数据,可以使List或者iterator, cmp和key都是函数,这两个函数作用与data的元素上产生一个结果,sorted方法根据这个结果来排序。 cmp(e1, e2) 是带两个参数的比较函数, 返回值: 负数: e1 < e2, 0: e1 == e2, 正数: e1 > e2. 默认为 None, 即用内建的比较函数. key 是带一个参数的...
Python lists have a built-insort()method that modifies the list in-place and asorted()built-in function that builds a new sorted list from an iterable. There are many ways to use them to sort data and there doesn't appear to be a single, central place in the various manuals describing...
Help on built-in function sort: sort(*, key=None, reverse=False) method of builtins.list instance Sort the list in ascending order and return None. The sort is in-place (i.e. the list itself is modified) and stable (i.e. the order of two equal elements is maintained). If a ...
list.sort⽅法会就地排序列表，也就是说不会把原列表复制⼀份。这也是这个⽅法的返回值是None的原因，提醒您本⽅法不会新建⼀个列表。在这种情况下返回None其实是Python的⼀个惯例：如果⼀个函数或者⽅法对对象进⾏的是就地改动，那它就应该返回None，好让调⽤者知道传⼊的参数发⽣了变动，...
Python sort方法 官方文档: sort(*,key=None,reverse=False) This method sorts the list in place, using only<comparisons between items. Exceptions are not suppressed - if any comparison operations fail, the entire sort operation will fail (and the list will likely be left in a partially modified...
