如何在输出中获取转义字符'\\\\'

有人可以帮助在我的配置单元中获取'\ \ \ \'（四个反推）插入覆盖查询输出。

我试过了：

beeline = "beeline -u 'jdbc:hive2:blahblah'"
exportDir = " /dev/targetdir "
presql =  ' INSERT OVERWRITE DIRECTORY \'' + exportDir + '\' ROW FORMAT DELIMITED FIELDS TERMINATED BY \',\' ' + 'ESCAPED BY \'\\\\\' NULL DEFINED AS \'\' '
sql = " select abc from xyz limit 10 "

>>> print(beeline + " -e " + '\"'+ presql + sql+'\"')

beeline -u 'jdbc:hive2blahblah' -e "INSERT OVERWRITE DIRECTORY '/dev/targetDir/' ROW FORMAT DELIMITED FIELDS TERMINATED BY ',' ESCAPED BY '\\' NULL DEFINED AS '' select abc from xyz limit 10"


#Expected O/p:

beeline -u 'jdbc:hive2blahblah' -e "INSERT OVERWRITE DIRECTORY '/dev/targetDir/' ROW FORMAT DELIMITED FIELDS TERMINATED BY ',' ESCAPED BY '\\\\' NULL DEFINED AS '' select abc from xyz limit 10"
