Python：1-8个数字中任意4个组合

测试目的

1-8通道取n个数组合，测试不同组合场景运行逻辑正确性

实现1：枚举法

 1 def test_loadTips_TwoChannels():
 2     """
 3     1-8通道任意2通道组合扎取
 4     """
 5     # 方法一：枚举法
 6     for a2 in range(1, 9):
 7         for b2 in range(a2 + 1, 9):
 8             load_tips({"Sequence": "Lane7TipsPos1", "Channels": [a2, b2], "IfIncrement": False})
 9             unload_tips({"Sequence": "Lane7TipsPos1", "Channels": [a2, b2], "IfIncrement": True})
10     reload_sequence("Lane7TipsPos1")
11 
12 
13 test_loadTips_TwoChannels()

实现2：Python标准库itertools

 1 def test_loadTips_ThreeChannel():
 2     """
 3     1-8通道任意3通道组合扎取
 4     """
 5     # 方法二：Python标准库itertools
 6     channel_list = [1, 2, 3, 4, 5, 6, 7, 8]
 7     for c in itertools.combinations(channel_list, 3):
 8         threeChannel = map(int, c)
 9         load_tips({"Sequence": "Lane1-TipSequence", "Channels": threeChannel, "IfIncrement": False})
10         unload_tips({"Sequence": "Lane1-TipSequence", "Channels": threeChannel, "IfIncrement": True})
11     reload_sequence("Lane1-TipSequence")
12 
13 
14 test_loadTips_ThreeChannel()

实现3：递归

 1 # *****************************************case:1-8通道7通道组合扎取正确*****************************************
 2 def test_loadTips_SevenChannel():
 3     """
 4     1-8通道7通道组合扎取
 5     :return:
 6     """
 7     # 方法三：递归法 从8个数中取7个数，不重复的，共计28种组合
 8     channel_list = [1, 2, 3, 4, 5, 6, 7, 8]
 9 
10     def combine(channel_list, l):
11         result = []
12         tmp = [0] * l
13         length = len(channel_list)
14 
15         def next_num(li=0, ni=0):
16             if ni == l:
17                 result.append(copy.copy(tmp))
18                 return
19             for lj in range(li, length):
20                 tmp[ni] = channel_list[lj]
21                 next_num(lj + 1, ni + 1)
22 
23         next_num()
24         return result
25 
26     for channel in combine(channel_list, 7):
27         # print channel
28         load_tips({"Sequence": "Lane1-TipSequence", "Channels": channel, "IfIncrement": False})
29         unload_tips({"Sequence": "Lane1-TipSequence", "Channels": channel, "IfIncrement": True})
30     reload_sequence("Lane1-TipSequence")
31 
32 
33 test_loadTips_SevenChannel()
