csvreader.dialect A read-only description of the dialect in use by the parser.

ac_out_buffer_size The asynchronous output buffer size (default 4096).

json.loads(s, encoding=None, cls=None, object_hook=None, parse_float=None, parse_int=None, parse_constant=None, object_pairs_hook=None, **kw) Deserialize s (a str instance containing a JSON document) to a Python object using this conversion table. The other arguments have the same meaning as in load(), except encoding which is ignored and deprecated.

curses.napms(ms) Sleep for ms milliseconds.

inspect.getcomments(object) Return in a single string any lines of comments immediately preceding the object’s source code (for a class, function, or method), or at the top of the Python source file (if the object is a module).

sys.ps1 sys.ps2 Strings specifying the primary and secondary prompt of the interpreter. These are only defined if the interpreter is in interactive mode. Their initial values in this case are '>>> ' and '... '. If a non-string object is assigned to either variable, its str() is re-evaluated each time the interpreter prepares to read a new interactive command; this can be used to implement a dynamic prompt.

hex() Return a string object containing two hexadecimal digits for each byte in the buffer. >>> m = memoryview(b"abc") >>> m.hex() '616263' New in version 3.5.

ndbm.close() Close the ndbm database.
