Data Types The modules described in this chapter provide a variety of specialized Python also provides some built-in data types, in particular, "dict", The following modules are documented in this chapter: * "datetime" — Basic date and time types * Available Types * "timedelta" Objects * "date" Objects * "datetime" Objects * "time" Objects * "tzinfo" Objects * "timezone" Objects * "strftime()" and "strptime()" Behavior * "calendar" — General calendar-related functions * "collections" — Container datatypes * "ChainMap" objects * "ChainMap" Examples and Recipes * "Counter" objects * "deque" objects * "deque" Recipes * "defaultdict" objects * "defaultdict" Examples * "namedtuple()" Factory Function for Tuples with Named Fields * "OrderedDict" objects * "OrderedDict" Examples and Recipes * "UserDict" objects * "UserList" objects * "UserString" objects * "collections.abc" — Abstract Base Classes for Containers * Collections Abstract Base Classes * "heapq" — Heap queue algorithm * Basic Examples * Priority Queue Implementation Notes * Theory * "bisect" — Array bisection algorithm * Searching Sorted Lists * Other Examples * "array" — Efficient arrays of numeric values * "weakref" — Weak references * Weak Reference Objects * Example * Finalizer Objects * Comparing finalizers with "__del__()" methods * "types" — Dynamic type creation and names for built-in types * Dynamic Type Creation * Standard Interpreter Types * Additional Utility Classes and Functions * Coroutine Utility Functions * "copy" — Shallow and deep copy operations * "pprint" — Data pretty printer * PrettyPrinter Objects * Example * "reprlib" — Alternate "repr()" implementation * Repr Objects * Subclassing Repr Objects * "enum" — Support for enumerations * Module Contents * Creating an Enum * Programmatic access to enumeration members and their attributes * Duplicating enum members and values * Ensuring unique enumeration values * Using automatic values * Iteration * Comparisons * Allowed members and attributes of enumerations * Restricted subclassing of enumerations * Pickling * Functional API * Derived Enumerations * IntEnum * IntFlag * Flag * Others * Interesting examples * Omitting values * Using "auto" * Using "object" * Using a descriptive string * Using a custom "__new__()" * OrderedEnum * DuplicateFreeEnum * Planet * How are Enums different? * Enum Classes * Enum Members (aka instances) * Finer Points * Supported "__dunder__" names * Supported "_sunder_" names * "Enum" member type * Boolean value of "Enum" classes and members * "Enum" classes with methods * Combining members of "Flag" |
