如何将值与反斜杠进行比较？

Question

if (message.value[0] == "/" or message.value[0] == "\"):
    do stuff.

我确信这是一个简单的语法错误，但是这个if语句有点问题。

Answer 1

这样试试：

if message.value[0] == "/" or message.value[0] == "\\":
  do_stuff

Answer 2

转义反斜杠：

if message.value[0] == "/" or message.value[0] == "\\":

从documentation：

The backslash (\) character is used to escape characters that otherwise have a special meaning, such as newline, backslash itself, or the quote character.

Answer 3

当您只需要检查相等性时，还可以简单地使用^{}运算符在一系列接受的元素中执行成员资格测试：

if message.value[0] in ('/', '\\'):
    do_stuff()
