.reverse()这个方法的返回值就是空 一般使用的时候直接 list.reverse()print(list)就行 该方法没有返回值,但是会对列表的元素进行反向排序。所以直接print(list)来查看反向排列的情况就好reverse原地逆反list你执行list.reverse()print(list)
y = "PYTHON TUTORIAL"y = y.lower()print(y)Output:pythontutorial18. sorted() sorted() 函数的工作原理是从可迭代对象中创建一个列表,然后按降序或升序排列其值: f = {1, 4, 9, 3} # 尝试在一个集sort = {"G":8, "A":5, "B":9, "F":3} # 尝试在一个字典print(sorted(f, reverse=...
10、将数组逆序输出-实现reverse a = [1,2,3,4,5,6] for i in a[::-1]: print(i,end=" ") 1. 2. 3. 对应位置的数进行交换 a = [1,2,3,4,5,6] for i in range(0,(len(a)-1)//2): temp = a[i] a[i] =a[len(a)-i-1] ...
```python class ListNode: def __init__(self, val=0, next=None): self.val = val self.next = next def reverse_linked_list(head): prev = None curr = head while curr: next_node = curr.next curr.next = prev prev = curr curr = next_node return prev # 测试 node1 = ListNode(1)...
8) reverse这个也是一样,使元素反向存放。 9) sort这个函数也是大家所熟知的,但是在使用上需要注意: sort排序是在原位置进行排序,即会重新排序目标,比如y=x.sort(),这样y是空值,x则已经排好了。与我们的想法不同,因此,应该这样y=x[:],y.sort(),而且要注意的是,千万不要y=x,因为这样,Python默认的是引用...
