datatable.FExpr.__xor__()¶
Compute bitwise XOR of x and y.
If x or 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 x or 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.
When both x and 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
operator xor). Beware, however, that ^ has higher precedence
than xor, so it is advisable to always use parentheses:
DT[(f.x == 0) ^ (f.y == 0), :]
Parameters¶
FExprThe arguments must be either FExprs, or expressions that can be
converted into FExprs.
FExprAn expression that evaluates x ^ y.
