從字典中刪除和存儲列表

Question

在python中，我有一個由以下內容組成的字典：

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

我正在嘗試從字典中刪除鍵控FOXP2_DOG並將其單獨放置在新字典中。 我嘗試了不同的方法： del和.remove無濟於事。

Answer 1

像這樣：

>>> 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
