[英]Python - How do i add an existing dictionary to a set of new keys
我的函數給了我以下格式的字典-
{
"key1": {
"deleted": [],
"inserted": []
},
"key2": {
"deleted": [
{
"end": 5,
"line": "",
"start": 5
}
但是,我希望輸出如下 -
{ "section1":
{
"name":"key1",
"deleted":[],
"inserted":[],
}
},
{ "section2":
{
"name":"key2",
"deleted":[],
"inserted":[],
}
},
{ "section3":
{
"name":"key3",
"deleted":[],
"inserted":[],
}
},
我寫的函數是-
diff_data = {}
with open('2018temp.json', 'w') as f1t, open('2019temp.json', 'w') as f2t:
json.dump(f1_dict, f1t)
json.dump(f2_dict, f2t)
for section in settings['includes']:
f1_text = f1_dict.get(section, [])
f2_text = f2_dict.get(section, [])
diffile = []
diff = difflib.Differ()
with open('diffile.txt', 'a') as f:
for line in diff.compare(f1_text, f2_text):
f.write(line + ('\n' if not line.endswith('\n') else ''))
if line.startswith(("-", "+", "?")):
diffile.append(line)
data = {'deleted': [], 'inserted': []}
for i, line in enumerate(diffile[:-1]):
if line.startswith('-'):
if diffile[i+1].startswith('?'): # Deletion and modification
updated_line = diffile[i+2]
update_start = re.search('[-+^]', diffile[i+1]).start()
update_end = re.search('[-+^][^-+^]*$', diffile[i+1]).start()
data['deleted'].append({'line': diffile[i+2][2:], 'start': update_start, 'end': update_end})
elif diffile[i+1].startswith('+') and i+2 < len(diffile) and diffile[i+2].startswith('?'):
pass # Addition and modification, do nothing
else:
data['deleted'].append(line[2:]) # Pure deletion
elif line.startswith('+'):
if diffile[i+1].startswith('?'): # Addition and modification
update_start = re.search('[-+^]', diffile[i+1]).start()
update_end = re.search('[-+^][^-+^]*$', diffile[i+1]).start()
data['inserted'].append({'line': line[2:], 'start': update_start, 'end': update_end})
else:
data['inserted'].append(line[2:]) # Pure addition
diff_data[section] = data
我試圖將diff_data[section] = data更改為 -
diff_data.setdefault('section',[]).append(data)
AttributeError: 'dict' object has no attribute 'append'
diff_data['section'].append(data)
AttributeError: 'dict' object has no attribute 'append'
diff_data.append({'section': [data]})
AttributeError: 'dict' object has no attribute 'append'
任何線索,我應該如何處理這個。 這似乎是一個簡單的問題,但我無法正確地將格式設置為所需的輸出。 如何編寫循環以將現有字典作為值插入到新的一組鍵中 - “section1, section2 ... ...”
我會復制字典,將原始鍵作為引用name
值,並創建一個新鍵來引用新的字典。
diff_data = {}
i = 1
for key, d in x.items():
new_dict = d.copy()
new_dict['name'] = key
new_key = "section_{}".format(str(i))
diff_data[new_key] = new_dict
i += 1
