刪除，並從字典

Question

存儲列表在蟒蛇， 我有以下組成的詞典：

[ ['FOXP2_MOUSE', 'AminoAcidSequence1'], ['FOXP2_RAT','AminoAcidSequence2'], ['FOXP2_DOG', 'AminoAcidSequence3'] ]. 

我試圖從字典中刪除鍵FOXP2_DOG並將其放置在單獨一個新的字典。我試過不同的方法：del和.remove無濟於事。

Answer 1

這樣的：

>>> my_list= [ ['FOXP2_MOUSE', 'AminoAcidSequence1'], ['FOXP2_RAT','AminoAcidSequence2'], ['FOXP2_DOG', 'AminoAcidSequence3'] ] 
>>> my_dict = dict(my_list) 
>>> my_dict 
{'FOXP2_RAT': 'AminoAcidSequence2', 'FOXP2_MOUSE': 'AminoAcidSequence1', 'FOXP2_DOG': 'AminoAcidSequence3'} 
>>> my_new_dict = {} 
>>> my_new_dict['FOXP2_MOUSE'] = my_dict.pop('FOXP2_MOUSE') 
>>> my_dict 
{'FOXP2_RAT': 'AminoAcidSequence2', 'FOXP2_DOG': 'AminoAcidSequence3'} 
>>> my_new_dict 
{'FOXP2_MOUSE': 'AminoAcidSequence1'} 

Answer 2

my_data = [ ['FOXP2_MOUSE', 'AminoAcidSequence1'], ['FOXP2_RAT','AminoAcidSequence2'], ['FOXP2_DOG', 'AminoAcidSequence3'] ] 

def custom_filter_data(data, key): 

    final_res = [] 

    for i in range(len(data)): 
     if data[i][0] == key: 
      final_res.append(data[i]) 
      del data[i] 

    return data, final_res 

results = custom_filter_data(my_data,'FOXP2_DOG') 
old = results[0] 
new = results[1] 
print old 
print new
