"\"7 BURY NEW ROAD  MANCHESTER","","","","Prestwich"

"""7 BURY NEW ROAD  MANCHESTER","","","","Prestwich"

"\"7 BURY NEW ROAD  MANCHESTER","","","","Prestwich"

Answer 1

我觉得有道理。csvreader使用\作为转义符，似乎无法更改。读取后，输入以以下结构开始：

DELIMITER - ESCAPED_QUOTATION_MARK

您的第一个CSVWriter转义符是“，因此第一个输出以

"""

您的第二个CSVWriter使用\转义，因此

"\"
