Serhiy Storchaka added the comment: This is ambiguous syntax. Unknown escapes consisting of '\' and ASCII letter were deprecated in 3.5 (run the interpreter with the option -Wa to see all warnings) and are errors since 3.6. Note that the string literal '[^\B]' itself produces a DeprecationWarning in 3.6.
