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 <`<` 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)`
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)`
