Screenshot of CSV file and corrupted cell
我猜这是我在发送前如何编码CSV文件的问题，我正在使用下面的代码。
def fileConversion(filename):
with open(filename,"rb") as attachment:
part = MIMEBase("application","octet-stream")
part.set_payload(attachment.read())
encoders.encode_base64(part)
stringmessage = part.as_string()
return stringmessage
请帮助！
