将相同键的值转换为list的方法有多种,以下是其中几种常见的方法:
result = {}
for key, value in data.items():
if key in result:
result[key].append(value)
else:
result[key] = [value]
print(result)
```
data = {'key1': 'value1', 'key2': 'value2', 'key3': 'value3', 'key4': 'value4', 'key5': 'value5', 'key6': 'value6', 'key7': 'value7', 'key8': 'value8', 'key9': 'value9', 'key10': 'value10', 'key11': 'value11', 'key12': 'value12', 'key13': 'value13', 'key14': 'value14', 'key15': 'value15', 'key16': 'value16', 'key17': 'value17', 'key18': 'value18', 'key19': 'value19', 'key20': 'value20', 'key21': 'value21', 'key22': 'value22', 'key23': 'value23', 'key24': 'value24', 'key25': 'value25', 'key26': 'value26', 'key27': 'value27', 'key28': 'value28', 'key29': 'value29', 'key30': 'value30', 'key31': 'value31', 'key32': 'value32', 'key33': 'value33', 'key34': 'value34', 'key35': 'value35', 'key36': 'value36', 'key37': 'value37', 'key38': 'value38', 'key39': 'value39', 'key40': 'value40', 'key41': 'value41', 'key42': 'value42', 'key43': 'value43', 'key44': 'value44', 'key45': 'value45', 'key46': 'value46', 'key47': 'value47', 'key48': 'value48', 'key49': 'value49', 'key50': 'value50'}
result = defaultdict(list)
for key, value in data.items():
result[key].append(value)
print(dict(result))
```
data = {'key1': 'value1', 'key2': 'value2', 'key3': 'value3', 'key4': 'value4', 'key5': 'value5', 'key6': 'value6', 'key7': 'value7', 'key8': 'value8', 'key9': 'value9', 'key10': 'value10', 'key11': 'value11', 'key12': 'value12', 'key13': 'value13', 'key14': 'value14', 'key15': 'value15', 'key16': 'value16', 'key17': 'value17', 'key18': 'value18', 'key19': 'value19', 'key20': 'value20', 'key21': 'value21', 'key22': 'value22', 'key23': 'value23', 'key24': 'value24', 'key25': 'value25', 'key26': 'value26', 'key27': 'value27', 'key28': 'value28', 'key29': 'value29', 'key30': 'value30', 'key31': 'value31', 'key32': 'value32', 'key33': 'value33', 'key34': 'value34', 'key35': 'value35', 'key36': 'value36', 'key37': 'value37', 'key38': 'value38', 'key39': 'value39', 'key40': 'value40', 'key41': 'value41', 'key42': 'value42', 'key43': 'value43', 'key44': 'value44', 'key45': 'value45', 'key46': 'value46', 'key47': 'value47', 'key48': 'value48', 'key49': 'value49', 'key50': 'value50'}
df = pd.DataFrame.from_dict(data, orient='index', columns=['value'])
result = df.groupby(df.index)['value'].apply(list).to_dict()
print(result)
```
以上是将相同键的值转换为list的几种常见方法,根据具体的需求和数据规模选择合适的方法进行处理。
