可以使用sorted函数来排序字典键并实现比较数字大小的操作。示例代码如下:
my_dict = {"a": 3, "b": 1, "c": 2}
# 对字典键进行排序
sorted_keys = sorted(my_dict)
# 按照排序后的键来遍历字典并比较数字大小
for key in sorted_keys:
if my_dict[key] > 2:
print(key, "has a value greater than 2")
else:
print(key, "has a value less than or equal to 2")
运行结果如下:
a has a value greater than 2
b has a value less than or equal to 2
c has a value less than or equal to 2
