定义一个函数,将一个列表旋转给定的位置数rotate_list 使用Python 的切片语法,按指定的位置数旋转列表。 专家: from collections import deque def rotate_list(numbers, positions): rotated_numbers = deque(numbers) rotated_numbers.rotate(positions) return list(rotated_numbers) numbers = [1, 2, 3, 4,...
#2.n.remove(item) will remove the actual item if it finds it: n.remove(1) # Removes 1 from the list, NOT the item at index 1 print n # prints [3, 5] #3.del(n[1]) #del is like .pop in that it will remove the item at the given index, but it won't return it: ...

Here, dict(a='foo', b=25, c='qux') creates a dictionary from the specified key/value pairs. Then, the double asterisk operator (**) unpacks it and passes the keywords to f().Putting It All Together Think of *args as a variable-length positional argument list, and **kwargs as a...
