y are multi-column expressions, then they must have the
same number of columns, and the
^ operator will be applied to each
corresponding pair of columns. If either
y are single-column
while the other is multi-column, then the single-column expression
will be repeated to the same number of columns as its opponent.
The XOR operator can only be applied to integer or boolean columns. The resulting column will have stype equal to the larger of the stypes of its arguments.
y are boolean, then the bitwise XOR operator is
equivalent to logical XOR. This can be used to combine several logical
conditions into a compound (since Python doesn’t allow overloading of
xor). Beware, however, that
^ has higher precedence
xor, so it is advisable to always use parentheses:
DT[(f.x == 0) ^ (f.y == 0), :]
The arguments must be either
FExprs, or expressions that can be
An expression that evaluates
x ^ y.
