编写一个函数，交换指定字典的key和value。
例如:dict1={'a':1, 'b':2, 'c':3} --> dict1={1:'a', 2:'b', 3:'c'}
def exchange(dict1):
交换指定字典的key和value
:param dict1: 字典
:return: 字典
result = dict(zip(dict1.values(), dict1.keys()))
return..
gen_rectangle1 (Rectangle, 30, 20, 100, 200)
gen_rectangle1 (Rectangle1, 330, 20, 400, 200)
intersection (Rectangle, Rectangle1, RegionIntersection)
count_obj (RegionIntersection, Number1)
union1 (RegionIntersection, RegionUnion)
count_obj (RegionUnion, Number2)
connection (RegionUnion, ConnectedRegions)
count_obj (ConnectedRegions, Number3)
