python - Logical operators for Boolean indexing in Pandas - Stack Overflow

@Indominus: The Python language itself requires that the expression x and y triggers the evaluation of bool(x) and bool(y).Python "first evaluates x; if x is false, its value is returned; otherwise, y is evaluated and the resulting value is returned." So the syntax x and y can not be used for element-wised logical-and since only x or y can be returned. In contrast, x & y triggers x.__and__(y) and the __and__ method can be defined to return anything we like. – unutbu
