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) # without __future__.division |
| Division | a / b |
truediv(a, b) # with __future__.division |
| Division | a // b |
floordiv(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 < |
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 > |
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) |
| Ordering | a < b |
lt(a, b) |
| Ordering | a <= b |
le(a, b) |
| Equality | a == b |
eq(a, b) |
| Difference | a != b |
ne(a, b) |
| Ordering | a >= b |
ge(a, b) |
| Ordering | a > b |
gt(a, b) |
