Python Standard Operators and Functions

Table B.2 represents the operators and (built-in and factory) functions that can be used with most standard Python objects as well as user-defined objects in which you have implemented their corresponding special methods.

Table B.2. Standard Type Operators and Functions

Operator/function	Description	Result[a]
String representation
''	Evaluatable string representation	str
Built-in and factory functions
cmp(obj1, obj2)	Compares two objects	int
repr(obj)	Evaluatable string representation	str
str(obj)	Printable string representation	str
type(obj)	Object type	type
Value comparisons
<	Less than	bool
>	Greater than	bool
<=	Less than or equal to	bool
>=	Greater than or equal to	bool
==	Equal to	bool
!=	Not equal to	bool
<>	Not equal to	bool
Object comparisons
is	The same as	bool
is not	Not the same as	bool
Boolean operators
not	Logical negation	bool
and	Logical conjunction	bool
or	Logical disjunction	bool

^[a] Boolean comparisons return either true or False.
