3.10.1 Mapping Operators to Functions

This table shows how abstract operations correspond to operator symbols in the Python syntax and the functions in the operator module.

Operation	Syntax	Function
Addition	a + b	add(a, b)
Concatenation	seq1 + seq2	concat(seq1, seq2)
Containment Test	o in seq	contains(seq, o)
Division	a / b	div(a, b)
Bitwise And	a & b	and_(a, b)
Bitwise Exclusive Or	a ^ b	xor(a, b)
Bitwise Inversion	~ a	invert(a)
Bitwise Or	a | b	or_(a, b)
Indexed Assignment	o[k] = v	setitem(o, k, v)
Indexed Deletion	del o[k]	delitem(o, k)
Indexing	o[k]	getitem(o, k)
Left Shift	a << b	lshift(a, b)
Modulo	a % b	mod(a, b)
Multiplication	a * b	mul(a, b)
Negation (Arithmetic)	- a	neg(a)
Negation (Logical)	not a	not_(a)
Right Shift	a >> b	rshift(a, b)
Sequence Repitition	seq * i	repeat(seq, i)
Slice Assignment	seq[i:j] = values	setslice(seq, i, j, values)
Slice Deletion	del seq[i:j]	delslice(seq, i, j)
Slicing	seq[i:j]	getslice(seq, i, j)
String Formatting	s % o	mod(s, o)
Subtraction	a - b	sub(a, b)
Truth Test	o	truth(o)
