[oeasy]python0051_ 转义_escape_字符_character_单引号_双引号_反引号_ 退格键

转义字符回忆上次内容上次研究的是进制转化10进制可以转化为其他形式binocthex其他进制也可以转化为10进制int可以设置base来决定转为多少进制回忆一下我们为什么会有八进制？因为需要用八进制输出转义字符\ooo把(ooo)8进制对应的ascii字符输出就如同\xhh把(hh)16进制对应的ascii字符输出比如输出\n、\r等那我想只输出\这个字符可以吗？\ 叫什么字符来着？转义字符\ ....

python中执行sql，如何escape掉单引号和双引号，就是插入的字符串中，包含引号如何处理？

python中执行sql比如：sql = 'UPDATE LINKS SET TITLE="{0}" WHERE id="3";'.format('a \"string\" in quote')这是我尝试做的用两个，但还是不可以插入带单引号或者双引号的条目，字符串中的单引号或者双引号不确定。
