如何使用“我的词典”中的常用字符串对新词典进行分组

Question

请参阅我前面的问题：How to extract the common words before particular symbol and find particular word

mydict = {"g18_84pp_2A_MVP1_GoodiesT0-HKJ-DFG_MIX-CMVP1_Y1000-MIX.txt" : 0,
          "g18_84pp_2A_MVP2_GoodiesT0-HKJ-DFG_MIX-CMVP2_Y1000-MIX.txt" : 1,
          "g18_84pp_2A_MVP3_GoodiesT0-HKJ-DFG_MIX-CMVP3_Y1000-MIX.txt" : 2,
          "g18_84pp_2A_MVP4_GoodiesT0-HKJ-DFG_MIX-CMVP4_Y1000-MIX.txt" : 3,
          "g18_84pp_2A_MVP5_GoodiesT0-HKJ-DFG_MIX-CMVP5_Y1000-MIX.txt" : 4,
          "g18_84pp_2A_MVP6_GoodiesT0-HKJ-DFG_MIX-CMVP6_Y1000-MIX.txt" : 5,
          "h18_84pp_3A_MVP1_GoodiesT1-HKJ-DFG-CMVP1_Y1000-FIX.txt" : 6,
          "g18_84pp_2A_MVP7_GoodiesT0-HKJ-DFG_MIX-CMVP7_Y1000-MIX.txt" : 7,
          "h18_84pp_3A_MVP2_GoodiesT1-HKJ-DFG-CMVP2_Y1000-FIX.txt" : 8,
          "h18_84pp_3A_MVP3_GoodiesT1-HKJ-DFG-CMVP3_Y1000-FIX.txt" : 9,
          "p18_84pp_2B_MVP1_GoodiesT2-HKJ-DFG-CMVP3_Y1000-FIX.txt" : 10}

我已经拿到了我的输出名dict

OutputNameDict = {'h18_84pp_3A_MVP_FIX': 1, 'p18_84pp_2B_MVP_FIX': 2, 'g18_84pp_2A_MVP_MIX': 0}

现在我要做的是使用我的公共字符串CaseNameString（参考上一个问题）和OutputNameDict中的值对三个新字典进行分组。

理想结果如下：

第1组。mydict0使用OutputNameDict中的值0和CaseNameString中的字符串g18_84pp_2A_MVP_GoodiesT0。你知道吗

mydict0 = {"g18_84pp_2A_MVP1_GoodiesT0-HKJ-DFG_MIX-CMVP1_Y1000-MIX.txt" : 0,               
           "g18_84pp_2A_MVP2_GoodiesT0-HKJ-DFG_MIX-CMVP2_Y1000-MIX.txt" : 1,
           "g18_84pp_2A_MVP3_GoodiesT0-HKJ-DFG_MIX-CMVP3_Y1000-MIX.txt" : 2,
           "g18_84pp_2A_MVP4_GoodiesT0-HKJ-DFG_MIX-CMVP4_Y1000-MIX.txt" : 3,
           "g18_84pp_2A_MVP5_GoodiesT0-HKJ-DFG_MIX-CMVP5_Y1000-MIX.txt" : 4,
           "g18_84pp_2A_MVP6_GoodiesT0-HKJ-DFG_MIX-CMVP6_Y1000-MIX.txt" : 5,
           "g18_84pp_2A_MVP7_GoodiesT0-HKJ-DFG_MIX-CMVP7_Y1000-MIX.txt" : 6}

第二组。mydict1在OutputNameDict中使用值1，在CaseNameString中使用字符串h18_84pp_3A_MVP_GoodiesT1。你知道吗

mydict1 ={"h18_84pp_3A_MVP1_GoodiesT1-HKJ-DFG-CMVP1_Y1000-FIX.txt" : 0,
          "h18_84pp_3A_MVP2_GoodiesT1-HKJ-DFG-CMVP2_Y1000-FIX.txt" : 1,
          "h18_84pp_3A_MVP3_GoodiesT1-HKJ-DFG-CMVP3_Y1000-FIX.txt" : 2}

第三组。mydict2在OutputNameDict中使用值2，在CaseNameString中使用字符串p18_84pp_2B_MVP_GoodiesT2。你知道吗

mydict2 ={"p18_84pp_2B_MVP1_GoodiesT2-HKJ-DFG-CMVP3_Y1000-FIX.txt" : 0}

有什么建议吗？有什么函数可以调用吗？你知道吗

Answer 1

我将OutputNameDict键更改为正则表达式模式，如下所示：

OutputNameDict = {'h18_84pp_3A_MVP.*FIX': 1, 'p18_84pp_2B_MVP.*FIX': 2, 'g18_84pp_2A_MVP.*MIX': 0}

然后，使用re正则表达式模块，使用该模块匹配mydict中的键，并将dictionary元素放入output_dictsdictionary中相应的键，如下所示

import collections
import re
output_dicts = collections.defaultdict(dict)

for k, v in mydict.iteritems():
    for pattern, suffix in OutputNameDict.iteritems():
        if re.match(pattern,k):
            output_dicts['mydict' + str(suffix)][k] = v
            break
    else:
        output_dicts['not matched'][k] = v

这将导致output_dicts字典填充如下

for k, v in output_dicts.iteritems():
    print k
    print v
    print

哪些输出

mydict1
{'h18_84pp_3A_MVP2_GoodiesT1-HKJ-DFG-CMVP2_Y1000-FIX.txt': 8, 
 'h18_84pp_3A_MVP3_GoodiesT1-HKJ-DFG-CMVP3_Y1000-FIX.txt': 9, 
 'h18_84pp_3A_MVP1_GoodiesT1-HKJ-DFG-CMVP1_Y1000-FIX.txt': 6}

mydict0
{'g18_84pp_2A_MVP1_GoodiesT0-HKJ-DFG_MIX-CMVP1_Y1000-MIX.txt': 0,
 'g18_84pp_2A_MVP2_GoodiesT0-HKJ-DFG_MIX-CMVP2_Y1000-MIX.txt': 1, 
 'g18_84pp_2A_MVP4_GoodiesT0-HKJ-DFG_MIX-CMVP4_Y1000-MIX.txt': 3, 
 'g18_84pp_2A_MVP5_GoodiesT0-HKJ-DFG_MIX-CMVP5_Y1000-MIX.txt': 4, 
 'g18_84pp_2A_MVP3_GoodiesT0-HKJ-DFG_MIX-CMVP3_Y1000-MIX.txt': 2, 
 'g18_84pp_2A_MVP6_GoodiesT0-HKJ-DFG_MIX-CMVP6_Y1000-MIX.txt': 5, 
 'g18_84pp_2A_MVP7_GoodiesT0-HKJ-DFG_MIX-CMVP7_Y1000-MIX.txt': 7}

mydict2
{'p18_84pp_2B_MVP1_GoodiesT2-HKJ-DFG-CMVP3_Y1000-FIX.txt': 10}
