我有以列表形式存儲的 dict 值。這是它的樣子：d = [{'Driveline': 'Rear-wheel drive', 'Hybrid': 'False', 'Classification': 'Automatic,Transmission', 'Number_of_Forward_Gears': 6, 'Fuel_Type': 'Gasoline', 'Length': 'first=prince,initial=p'},{'Driveline': 'Rear-wheel drive', 'Hybrid': 'False', 'Classification': 'Automatic,Transmission', 'Number_of_Forward_Gears': 6, 'Fuel_Type': 'Gasoline', 'Length': 'first=steven,initial=s'}]在這里，在 keyLength中，我有兩個值。first=steven,initial=s 我想拆分這些值并創(chuàng)建兩個新字段并將其以更新的形式存儲在字典中。所需輸出：d = [{'Driveline': 'Rear-wheel drive', 'Hybrid': 'False', 'Classification': 'Automatic,Transmission', 'Number_of_Forward_Gears': 6, 'Fuel_Type': 'Gasoline', 'Length': 'first=prince,initial=p','first':'prince','initial':'p'},{'Driveline': 'Rear-wheel drive', 'Hybrid': 'False', 'Classification': 'Automatic,Transmission', 'Number_of_Forward_Gears': 6, 'Fuel_Type': 'Gasoline', 'Length': 'first=steven,initial=s','first':'steven','initial':'s'}]這是我嘗試過的程序：d = [{'Driveline': 'Rear-wheel drive', 'Hybrid': 'False', 'Classification': 'Automatic,Transmission', 'Number_of_Forward_Gears': 6, 'Fuel_Type': 'Gasoline', 'Length': 'first=prince,initial=p'},{'Driveline': 'Rear-wheel drive', 'Hybrid': 'False', 'Classification': 'Automatic,Transmission', 'Number_of_Forward_Gears': 6, 'Fuel_Type': 'Gasoline', 'Length': 'first=steven,initial=s'}]field_to_split = "Length"split_using1 = ','split_using2 = '='b =[]for i in d: s = i[field_to_split].split(split_using1) print(s) b.append(s) #print(s)print(b)我怎樣才能使這成為可能...

使用簡單的迭代。
前任：
d = [
{'Driveline': 'Rear-wheel drive', 'Hybrid': 'False', 'Classification': 'Automatic,Transmission', 'Number_of_Forward_Gears': 6, 'Fuel_Type': 'Gasoline', 'Length': 'first=prince,initial=p'},
{'Driveline': 'Rear-wheel drive', 'Hybrid': 'False', 'Classification': 'Automatic,Transmission', 'Number_of_Forward_Gears': 6, 'Fuel_Type': 'Gasoline', 'Length': 'first=steven,initial=s'}
]
for i in d:
for j in i['Length'].split(","): #Split string by comma
i.update(dict([j.split("=")])) #Split string by eq sign and use dict() method to create a dictionary
輸出：
[{'Classification': 'Automatic,Transmission',
'Driveline': 'Rear-wheel drive',
'Fuel_Type': 'Gasoline',
'Hybrid': 'False',
'Length': 'first=prince,initial=p',
'Number_of_Forward_Gears': 6,
'first': 'prince',
'initial': 'p'},
{'Classification': 'Automatic,Transmission',
'Driveline': 'Rear-wheel drive',
'Fuel_Type': 'Gasoline',
'Hybrid': 'False',
'Length': 'first=steven,initial=s',
'Number_of_Forward_Gears': 6,
'first': 'steven',
'initial': 's'}]
