Should I add NEWS entry here? I think the change only has little change for users so I didn’t add it for now. If needed, please kindly let me know, thanks! |

The binary arithmetic operations grammar incorrectly showed the @ operator as right-associative (m_expr "@" m_expr) while all other multiplicative operators are left-associative (m_expr "*" u_expr).
According to PEP 465, the @ operator should have the same associativity as *. The actual parser implementation in Grammar/python.gram correctly implements left-associativity, but the documentation was inconsistent.
