Syntax object.__rsub__(self, other) The Python __rsub__() method implements the reverse subtraction operation that is subtraction with reflected, swapped operands. So, when you call x – y, Python attempts to call x.__sub__(y). Only if the method is not implemented on the left operand, Python attempts to call __rsub__ on the right operand and if this isn’t … Read more
Syntax object.__radd__(self, other) The Python __radd__() method implements the reverse addition operation that is addition with reflected, swapped operands. So, when you call x + y, Python attempts to call x.__add__(y). Only if the method is not implemented on the left operrand, Python attempts to call __radd__ on the right operand and if this isn’t … Read more
Syntax object.__rxor__(self, other) The Python __rxor__() method implements the reverse Bitwise XOR ^ operation with reflected, swapped operands. So, when you call x ^ y, Python attempts to call x.__xor__(y). If the method is not implemented, Python attempts to call __rxor__ on the right operand and if this isn’t implemented either, it raises a TypeError. … Read more
Syntax object.__xor__(self, other) The Python __xor__() method implements the built-in Bitwise XOR ^ operation. So, when you cal x ^ y, Python attempts to call x.__xor__(y). If the method is not implemented, Python first attempts to call __rxor__ on the right operand and if this isn’t implemented either, it raises a TypeError. We call this … Read more
Syntax object.__or__(self, other) The Python __or__() method implements the built-in Bitwise OR | operation. So, when you cal x | y, Python attempts to call x.__or__(y). If the method is not implemented, Python first attempts to call __ror__ on the right operand and if this isn’t implemented either, it raises a TypeError. We call this … Read more
Syntax object.__and__(self, other) The Python __and__() method implements the built-in Bitwise AND & operation. So, when you cal x & y, Python attempts to call x.__and__(y). If the method is not implemented, Python first attempts to call __rand__ on the right operand and if this isn’t implemented either, it raises a TypeError. We call this … Read more
Syntax object.__rshift__(self, other) The Python __rshift__() method implements the built-in >> operation. So, when you cal x >> y, Python attempts to call x.__rshift__(y). If the method is not implemented, Python first attempts to call __rrshift__ on the right operand and if this isn’t implemented either, it raises a TypeError. We call this a “Dunder … Read more
Syntax object.__lshift__(self, other) The Python __lshift__() method implements the built-in << operation. So, when you cal x << y, Python attempts to call x.__lshift__(y). If the method is not implemented, Python first attempts to call __rlshift__ on the right operand and if this isn’t implemented either, it raises a TypeError. We call this a “Dunder … Read more
Syntax object.__pow__(self, other) The Python __pow__() method implements the built-in exponentiation operation. So, when you call pow(a, b) or a ** b, Python attempts to call x.__pow__(y). If the method is not implemented, Python first attempts to call __rpow__ on the right operand and if this isn’t implemented either, it raises a TypeError. We call … Read more
Syntax object.__divmod__(self, other) The Python __divmod__() method implements the built-in divmod operation. So, when you call divmod(a, b), Python attempts to call x.__divmod__(y). If the method is not implemented, Python first attempts to call __rdivmod__ on the right operand and if this isn’t implemented either, it raises a TypeError. We call this a “Dunder Method” … Read more
Syntax object.__mod__(self, other) The Python __mod__() method implements the modulo operation % that per default returns the remainder of dividing the left by the right operand. Internally, Python attempts to call x.__mod__(y) to implement the modulo operation x%y. If the method is not implemented, Python first attempts to call __rmod__ on the right operand and … Read more
Syntax object.__floordiv__(self, other) The Python __floordiv__() method implements the integer division operation // called floor division—as opposed to the true division operation /. For example to evaluate the expression x // y, Python attempts to call x.__floordiv__(y). If the method is not implemented, Python first attempts to call __rfloordiv__ on the right operand and if … Read more
