排序和反转

# sorted()函数
data_dict = {i: i*2 for i in range(4, 10)}
print(data_dict)
sorted_list = sorted(data_dict.items(), key=lambda x: x[0], reverse=False)
print(sorted_list)

{4: 8, 5: 10, 6: 12, 7: 14, 8: 16, 9: 18}
[(4, 8), (5, 10), (6, 12), (7, 14), (8, 16), (9, 18)]

number = list(range(10))
# 升序
number.sort()
print(‘这是升序后的结果‘, number)
# 降序
number.sort(reverse=True)
print(‘这是降序后的结果‘, number)

这是升序后的结果 [0, 1, 2, 3, 4, 5, 6, 7, 8, 9]
这是降序后的结果 [9, 8, 7, 6, 5, 4, 3, 2, 1, 0]
