转义MySQL LOAD DATA INFILE命令

Question

我想在Python3.6中转义这个命令，因为我想使用它来运行大量的csv文件。

for filename in glob.glob(CSV_FOLDER_LOCATION + "/*.csv"):
    # Adds quotes to filename because of the problem caused by spaces in path names
    quoted_filename = '"' + filename + '"'
    os.system(MYSQL_LOCATION + r" -u root LOAD DATA INFILE " + quoted_filename + " INTO TABLE " + TABLE_NAME +
              r" CHARACTER SET ascii FIELDS TERMINATED BY ',' ENCLOSED BY '"' LINES TERMINATED BY '/n' IGNORE 1 LINES")

逗号显示为空格。这是输出：

C:/Program Files/MySQL/MySQL Server 5.7/bin/mysql.exe -u root LOAD DATA INFILE "C:/prog/csv/CSVFiles\CC19711977ZWEIG-ZZ.csv" INTO TABLE vcc2.tmp_cards CHARACTER SET ascii FIELDS TERMINATED BY   ENCLOSED BY '"' LINES TERMINATED BY '/n' IGNORE 1 LINES

转义该字符串的正确方法是什么？

也许我真的很粗鲁，遗漏了一些明显的东西，但我如何才能“原始字符串”它的C风格？

以这样的方式进行转义：

os.system(
            r"LOAD DATA LOCAL INFILE " + '"' + CSV_FOLDER_LOCATION + '/' + filename + '"' + " INTO TABLE " + TABLE_NAME +
            r' CHARACTER SET ascii FIELDS TERMINATED BY ' + '\',\'' + ' ENCLOSED BY ' + '\'"\'' +
            ' LINES TERMINATED BY ' + '\'\\n\'' + ' IGNORE 1 LINES')
