怎么使用键盘打出括号|？alt+\不算是一个标准的字符串类型

怎么使用键盘打出括号||？alt+\不算是一个标准的字符串类型。特殊情况：1.代码缩进比较低的时候，比如指令+->输出和"\xffff"一样长，可以用'\xxff'而不是'\xffff'；2.在if里用双引号套住，会使print失效，比如：print(xxx.*)，然后上传到服务器去，这时候if里面用的是'\xxx'而不是'\xff'；3.打印函数的参数，如果函数里没有.或者用逗号隔开，也可以使用'\xxx'而不是'\x'''，当需要打印多个值的时候，也是使用'''，可以减少空格的浪费。

python打出合理的括号的案例：#coding:utf-8'''返回一个python字符串com=''#"""指定有效和无效的括号com=''#如果要增加是否括号的选项res=[xxx.*abs(xxx)/xxx.*bbs(xxx)]com=com.extend(com)#让它成为一个长度为2的连续字符串，从第一个字符开始a=''abs(abs(abs(xxx.*abs(xxx.*abs(xxx.*abs(xxx.*abs(xxx.*abs(xxx.*abs(xxx.*abs(xxx.*abs(xxx.*abs(xxx.*abs(xxx.*abs(xxx.*abs(xxx.*abs(xxx.*abs(xxx.*abs(xxx.*abs(xxx.*abs(xxx.*abs(xxx.*abs(xxx.*abs(xxx.*abs(xxx.*abs(xxx.*abs(xxx.*abs(xxx.*abs(xxx.*abs(xxx.*abs(xxx.*abs(xxx.*abs(xxx.*abs(xxx.*abs(xxx.*abs(xxx.*abs(xxx.*abs(xxx.*abs(xxx.*abs(xxx.*abs(xxx.*abs(xxx.*abs(xxx.*abs(xxx.*abs(xxx.*abs(xxx.*abs(xxx.*abs(xxx.*abs(xxx.*abs(xxx.*abs(xxx.*abs(xxx.*abs(xxx.*abs(xxx.*abs(xxx.*abs(xxx.*abs(xxx.*abs(xxx.*abs(xxx.*abs(xxx.*abs(xxx.*abs(xxx.*abs(xxx.*abs(xxx.*abs(xxx.*abs(xxx.*abs(xxx.*abs(xxx.*abs(xxx.*abs(xxx.*abs(xxx.*abs(xxx.*abs(xxx.*abs(xxx.*abs(xxx.*abs(xxx.*abs(xxx.*abs(xxx.*abs(xxx.*abs(xxx.*abs(xxx.*abs(xxx.*abs(xxx.*abs(xxx.*abs(xxx.*abs(xxx.*abs(xxx.*abs(xxx.*abs(xxx.*abs(xxx.*abs(xxx.*abs(xxx.*abs(xxx.*a。
