但我試圖從串列中提取資料并附加到一個具有不同列的新 csv 中，使其看起來整潔干凈
所以，我在這里嘗試代碼
writer = csv.DictWriter(response_data, fieldnames=['Farmer Name', 'Mobile', 'Irrigation Type', 'Batch Status',
'Soil Parameters',
'Water Parameters', 'Crop Name', 'Farm Status', 'Farm Type',
'Franchise Type', 'Farm Total Acerage', 'Batch Acerage',
'Farm Health(%)', 'Historical Yield(/Acre)',
'Expected Produce',
'Actual Yield(/Acre)', 'Actual Produce', 'Crop health(%)',
'Stage', 'SOP Adherence', 'Assignee', 'Sub Farmer',
'Last Activity Update', 'Exp. Delivery Date'], delimiter=",")
writer.writeheader()
for docs in data.keys():
writer.writerow(
{"Farmer Name": docs.get('username'), "Mobile": docs.get('mobile')
"Irrigation Type": data.get('irrigation_type'), "Batch Status": data.get('batch_status'),
"Soil Parameters": {'N:-': data.get('soil_n'), 'P:-': data.get('soil_p'),
'K:-': data.get('soil_k')},
"Water Parameters": {'ec:-': data.get('water_ec'), 'pH:-': data.get('water_ph'), },
"Crop Name": data.get('commodity_name'), "Farm Status": data.get('farm_status'),
"Farm Type": data.get('farm_type'),
"Franchise Type": data.get('franchise_type'), "Farm Total Acerage": data.get('total_acerage'),
"Batch Acerage": data.get('batch_count'), "Farm Health(%)": data.get('farm_health'),
"Historical Yield(/Acre)": data.get(''),
"Expected Produce": data.get('expected_production'), "Actual Yield(/Acre)": data.get('username'),
"Actual Produce": data.get('username'), "Crop health(%)": data.get('username'),
"Stage": data.get('stage'),
"SOP Adherence": data.get('sope'),
"Last Activity Update": data.get('end_date'),
"Exp. Delivery Date": data.get('expected_delivery_date')
})
以便從該字典中提取資料并繼續作為甲硫氨酸列附加在 cdv 檔案上
但它顯示一個錯誤
AttributeError: 'str' object has no attribute 'get'
我無法從字典中獲取標題中的列值
uj5u.com熱心網友回復：
首先，令人困惑的是，您有一個名為 的 dict data，其中有一個名為 的鍵"data"，并且您正在docs使用名為 的鍵在 dict中迭代"docs"。
但是，錯誤是因為您正在迭代data.keys()，它為每個值回傳一個字串。
一個說明性的例子：
my_dict = {
"foo" : "bar",
"baz" : "luhrmann"
}
for each_key in my_dict.keys():
print(f"{each_key} : {type(each_key)}")
這將回傳：
foo : <class 'str'>
baz : <class 'str'>
因此，在該行中docs.get('username')，您嘗試get在字串上呼叫該方法。該錯誤告訴您字串沒有此方法。我認為你正在嘗試做的是data['docs'].get('username')。
