當我從 python 發送電子郵件時，出現錯誤“浮動”對象沒有屬性“編碼”。這成功運行了 6-7 天，沒有任何問題。def create_message(send_from, send_to, cc_to, subject, plain_text_body): message = MIMEMultipart('alternative') message['From'] = send_from message['To'] =send_to message['Cc'] = cc_to message['Date'] = formatdate(localtime=True) message['Subject'] = subject message.attach(MIMEText(plain_text_body, 'plain')) return messagedef add_attachment_from_local_disk(message, path): with open(path, "rb") as file: part = MIMEApplication(file.read(),Name=basename(path)) part['Content-Disposition'] = 'attachment; filename="%s"' % basename(path) message.attach(part) def send_message(message): print(message) client = boto3.client("ses",region_name='eu-west-1') response = client.send_raw_email(RawMessage = {"Data": message.as_string()})for i, row in final_email.iterrows(): subject = row["Subject"] to_address = row['fba_to__notifications'] or row['lsp_escalation_back_up'] or "[email protected]" cc_list = row['cc_list'] send_from="[email protected]" message = create_message(send_from,to_address, cc_list, subject, plain_text_body=body) send_message(message)錯誤~\AppData\Local\Continuum\anaconda3\lib\email\_policybase.py in _fold(self, name, value, sanitize) 367 if self.max_line_length is not None: 368 maxlinelen = self.max_line_length--> 369 parts.append(h.encode(linesep=self.linesep, maxlinelen=maxlinelen)) 370 parts.append(self.linesep) 371 return ''.join(parts)AttributeError: 'float' object has no attribute 'encode'如何解決這個問題？

該錯誤表明庫在需要字符串的地方收到了一個浮點數。從您的代碼中，我希望其中一個body或一個字段final_email包含一個浮點數。
由于數據框中的空值，浮點數是 NaN 我不會感到驚訝。為了確保（或使您的代碼更健壯），您可以嘗試過濾異常并顯示有問題的值：
for i, row in final_email.iterrows():
subject = row["Subject"]
to_address = row['fba_to__notifications'] or row['lsp_escalation_back_up'] or "[email protected]"
cc_list = row['cc_list']
send_from="[email protected]"
try:
message = create_message(send_from,to_address, cc_list, subject, plain_text_body=body)
except AttributeError as e:
print('Error composing email', send_from,to_address, cc_list, subject, body, '\n', e)
# raise # optionaly re-raise the exception if you want to stop processing
send_message(message)
無論如何，這里還有另一個問題。NaN被視為True在 Python 代碼中轉換為布爾值時。因此，如果它是 NaN，to_address賦值將不會回退到表達式。or因此，您應該combine_first在有意義的情況下選擇相關列 ( final_email['fba_to__notifications'].combine_first(final_email['lsp_escalation_back_up'].fillna('[email protected]'))，或者明確測試 NaN 值：
to_address = row['fba_to__notifications'] if not np.isnan(row['fba_to__notifications']) \
else row['lsp_escalation_back_up'] if not isnan(row['lsp_escalation_back_up']) \
else "[email protected]"
