new
— 创建运行时内部对象
¶
Deprecated since version 2.6:
The
new
module has been removed in Python 3. Use the
types
module’s classes instead.
The
new
module allows an interface to the interpreter object creation functions. This is for use primarily in marshal-type functions, when a new object needs to be created “magically” and not by using the regular creation functions. This module provides a low-level interface to the interpreter, so care must be exercised when using this module. It is possible to supply non-sensical arguments which crash the interpreter when the object is used.
The

new.
实例
(
class
[
,

]
)
¶
This function creates an instance of
class
with dictionary
dict
without calling the
__init__()
constructor. If
dict
被省略或
None
, a new, empty dictionary is created for the new instance. Note that there are no guarantees that the object will be in a consistent state.

¶
Returns a (Python) function with the given code and globals. If
name
is given, it must be a string or
None
. If it is a string, the function will have the given name, otherwise the function name will be taken from
code.co_name
。若
argdefs
is given, it must be a tuple and will be used to determine the default values of parameters. If
closure
is given, it must be
None
or a tuple of cell objects containing objects to bind to the names in
