vertica-python supports default mapping to SQL literals for many standard Python types (str, bytes, bool, int, float, decimal.Decimal, tuple, list, set, dict, datetime.datetime, datetime.date, datetime.time, uuid.UUID). For complex types, in some cases, you may need explicit typecasting ...
Unpack memoryview into tuple of: type, version, width, and height. Delete references to release the memory associated with the memoryview instances. Note that slicing a memoryview returns a new memoryview, without copying bytes (Leonardo Rochael—one of the technical reviewers—pointed out that even...

the game board. One player has the black pieces; the other has thewhite pieces. Players alternate turns. A player may not move an opponents piece. A move consists of moving a piecediagonally (forward from the player’s side) to an adjacent unoccupied square. If the adjacent square contains...
Using ABC as a base class has essentially the same effect as specifying metaclass=abc.ABCMeta, but is simpler to type and easier to read. (Contributed by Bruno Dupuis in bpo-16049.) aifc The getparams() method now returns a namedtuple rather than a plain tuple. (Contributed by Claudiu ...
They may be any immutable type, such as floating-point (real) numbers, strings, or tuples. You can assign a value to a key, even if that key isn’t in the dictionary to begin with; in that case, a new item will be created. you could use string formatting to format all the ...
