我想將 Python 中的字典從字典 1 轉換為字典 2，如下所示。
transaction = {
"trans_time": "14/07/2015 10:03:20",
"trans_type": "DEBIT",
"description": "239.95 USD DHL.COM TEXAS USA",
}
我想將上面的字典轉換為以下
transaction = {
"trans_time": "14/07/2015 10:03:20",
"trans_type": "DEBIT",
"description": "DHL.COM TEXAS USA",
"amount": 239.95,
"currency": "USD",
"location": "TEXAS USA",
"merchant_name": "DHL"
}
我嘗試了以下但沒有奏效
dic1 = {
"trans_time": "14/07/2015 10:03:20",
"trans_type": "DEBIT",
"description": "239.95 USD DHL.COM TEXAS USA"
}
print(type(dic1))
copiedDic = dic1.copy()
print("copiedDic = ",copiedDic)
updatekeys = ['amount', 'currency', 'merchant_name', 'location', 'trans_category']
for key in dic1:
if key == 'description':
list_words = dic1[key].split(" ")
newdict = {updatekeys[i]: x for i, x in enumerate(list_words)}
copiedDic.update(newdict)
print(copiedDic)
我得到以下結果
{
'trans_time': '14/07/2015 10:03:20',
'trans_type': 'DEBIT',
'description': '239.95 USD DHL.COM TEXAS USA',
'amount': '239.95',
'currency': 'USD',
'merchant_name': 'DHL.COM',
'location': 'TEXAS',
'trans_category': 'USA'
}
我的預期輸出應如下所示：
transaction = {
"trans_time": "14/07/2015 10:03:20",
"trans_type": "DEBIT",
"description": "DHL.COM TEXAS USA",
"amount": 239.95,
"currency": "USD",
"location": "TEXAS USA",
"merchant_name": "DHL"
}

我認為將值轉換為單詞陣列并決議它會更容易。在這里，從字典字串 'transaction['description']' 創建了一個單詞陣列 'aaa'。如果有多個單詞（陣列元素），則使用“join”將陣列轉回字串。貨幣值本身從字串轉換為小數格式。在 'merchant_name' 中，取到該點的段。
transaction = {
"trans_time": "14/07/2015 10:03:20",
"trans_type": "DEBIT",
"description": "239.95 USD DHL.COM TEXAS USA",
}
aaa = transaction['description'].split()
transaction['description'] = ' '.join(aaa[2:])
transaction['amount'] = float(aaa[0])
transaction['currency'] = aaa[1]
transaction['location'] = ' '.join(aaa[3:])
transaction['merchant_name'] = aaa[2].partition('.')[0]
print(transaction)
輸出
{
'trans_time': '14/07/2015 10:03:20',
'trans_type': 'DEBIT',
'description': 'DHL.COM TEXAS USA',
'amount': 239.95,
'currency': 'USD',
'location': 'TEXAS USA',
'merchant_name': 'DHL'}

如果要轉換，則不需要復制到原始字典。
只需執行以下操作：
new_keys = ['amount', 'currency', 'merchant_name', 'location', 'trans_category']
values = transaction["description"].split(' ')
for idx, key in enumerate(new_keys):
if key == "amount":
transaction[key] = float(values[idx])
else:
transaction[key] = values[idx]
