Hi. I just want to know why is and, or operators behaving like this. The behavior is described in https://bugs.python.org/issue43833#msg390996. Moreover I researched a little more and found out even if __and__, __or__ methods are defined the and, or operators doesn't seem to work. As Serhiy described in https://bugs.python.org/issue43833#msg390998 the parser reads [0x1for x in (1,2)] as [0x1f or x in (1,2)] which is the parser's fault but why is the or operator behaving like that?
