Typically, backslashes are seen only as part of escape sequences. Therefore, the use of a backslash outside of a raw string or escape sequence looks suspiciously like a broken escape sequence. 


Characters recognized as escape-able are: ``++abfnrtvox\'"++``

s = "Hello world."
t = "Nice to \\ meet you"
u = r"Let's have \ lunch"  // raw string
