摘要

全文介绍系统内置 pickle 模块、函数、类及类的方法和属性。
它通过代码抓取并经AI智能翻译和人工校对。
是一部不可多得的权威字典类工具书。它是系列集的一部分。后续陆续发布、敬请关注。【原创：AhcaoZhu大侠】

说明

序列化模块 pickle, 反序列化模块 cPickle，python后续版本命名规范化后，反序列化模块为 _pickle。
由于两个模块具有较强相关性，故合为一篇文章，不再单独成文。

37 _pickle.Pickler

Pickler, _pickle.Pickler, module=_pickle

这需要一个二进制文件来写入pickle数据流。
可选参数*protocol*告诉pickler使用给定的协议;支持的协议类型为:0、1、2、3、4。
默认协议为3;为Python 3设计的向后不兼容协议。
指定负协议版本将选择支持的最高协议版本。使用的协议越高级，读取生成的pickle所需的Python版本就越新。
*file*参数必须有一个write()方法，该方法接受单个字节的论点。
因此，它可以是为二进制文件打开的文件对象写作，是一种爱。BytesIO实例，或任何其他满足的自定义对象这个接口。
如果*fix_imports*为True且protocol小于3,pickle将尝试将新的Python 3名称映射到Python中使用的旧模块名称2，
这样pickle数据流就可以用Python 2读取。

data

1 bin=<member ‘bin’ of ‘_pickle.Pickler’ objects> kind:data type:member_descriptor class:<class ‘_pickle.Pickler’>
2 dispatch_table=<member ‘dispatch_table’ of ‘_pickle.Pickler’ objects> kind:data type:member_descriptor class:<class ‘_pickle.Pickler’>
3 fast=<member ‘fast’ of ‘_pickle.Pickler’ objects> kind:data type:member_descriptor class:<class ‘_pickle.Pickler’>
4 memo=<attribute ‘memo’ of ‘_pickle.Pickler’ objects> kind:data type:getset_descriptor class:<class ‘_pickle.Pickler’>
5 persistent_id=<attribute ‘persistent_id’ of ‘_pickle.Pickler’ objects> kind:data type:getset_descriptor class:<class ‘_pickle.Pickler’>

method

6 clear_memo()

kind=method class=Pickler objtype=method_descriptor

清除pickler的“备忘录”。
memo是一种数据结构，它记住pickle器已经看过哪些对象，因此共享或递归对象是根据引用而不是根据值进行pickle的。
这种方法在重复使用酸洗器时很有用。

7 dump()

kind=method class=Pickler objtype=method_descriptor

将给定对象的pickle表示写入打开的文件。

38 _pickle.Unpickler

Unpickler, _pickle.Unpickler, module=_pickle

这需要一个二进制文件来读取pickle数据流。
pickle的协议版本是自动检测的，因此不需要任何协议参数。超过pickle对象表示的字节将被忽略。
参数*file*必须有两个方法，一个read()方法接受一个整数参数，另一个readline()方法不需要参数。
这两个方法都应该返回字节。因此，*file*可以是打开用于读取的二进制文件对象，即io.BytesIO对象，或满足此接口的任何其他自定义对象。
可选关键字参数是*fix_imports*， *encoding*和*errors*，它们用于控制Python 2生成的pickle流的兼容性支持。
如果*fix_imports*为True, pickle将尝试将旧的Python 2名称映射到Python 3中使用的新名称。
*encoding*和*errors*告诉pickle如何解码Python 2 pickle的8位字符串实例;它们分别默认为'ASCII'和'strict'。
*encoding*可以是'bytes'，将这些8位字符串实例读取为bytes对象。

data

1 memo=<attribute ‘memo’ of ‘_pickle.Unpickler’ objects> kind:data type:getset_descriptor class:<class ‘_pickle.Unpickler’>
2 persistent_load=<attribute ‘persistent_load’ of ‘_pickle.Unpickler’ objects> kind:data type:getset_descriptor class:<class ‘_pickle.Unpickler’>

method

3 find_class()

kind=method class=Unpickler objtype=method_descriptor

从指定的模块返回一个对象
。如果需要，将导入模块。
子类可以重写此方法(例如，限制任意类和函数的解pickle)。
当需要类或函数对象时调用此方法。传递的两个参数都是str对象。

4 load()

kind=method class=Unpickler objtype=method_descriptor

装上pickle。从构造函数中给定的打开文件对象读取pickle对象表示，并返回其中指定的重构对象层次结构。

类

1 _pickle.Pickler

Pickler, _pickle.Pickler, module=_pickle

这需要一个二进制文件来写入pickle数据流。（参见前面）

data

1 bin=<member ‘bin’ of ‘_pickle.Pickler’ objects> kind:data type:member_descriptor class:<class ‘_pickle.Pickler’>
2 dispatch_table=<member ‘dispatch_table’ of ‘_pickle.Pickler’ objects> kind:data type:member_descriptor class:<class ‘_pickle.Pickler’>
3 fast=<member ‘fast’ of ‘_pickle.Pickler’ objects> kind:data type:member_descriptor class:<class ‘_pickle.Pickler’>
4 memo=<attribute ‘memo’ of ‘_pickle.Pickler’ objects> kind:data type:getset_descriptor class:<class ‘_pickle.Pickler’>
5 persistent_id=<attribute ‘persistent_id’ of ‘_pickle.Pickler’ objects> kind:data type:getset_descriptor class:<class ‘_pickle.Pickler’>

method

6 clear_memo()

kind=method class=Pickler objtype=method_descriptor

清除pickler的“备忘录”。（参见前面）

7 dump()

kind=method class=Pickler objtype=method_descriptor

将给定对象的pickle表示写入打开的文件。

2 _pickle.Unpickler

Unpickler, _pickle.Unpickler, module=_pickle

这需要一个二进制文件来读取pickle数据流。（参见前面）

data

1 memo=<attribute ‘memo’ of ‘_pickle.Unpickler’ objects> kind:data type:getset_descriptor class:<class ‘_pickle.Unpickler’>
2 persistent_load=<attribute ‘persistent_load’ of ‘_pickle.Unpickler’ objects> kind:data type:getset_descriptor class:<class ‘_pickle.Unpickler’>

method

3 find_class()

kind=method class=Unpickler objtype=method_descriptor

从指定的模块返回一个对象。（参见前面）

4 load()

kind=method class=Unpickler objtype=method_descriptor

装上泡菜。从构造函数中给定的打开文件对象读取pickle对象表示，并返回其中指定的重构对象层次结构。

3 _pickle.PickleError

PickleError, _pickle.PickleError, module=_pickle

4 _pickle.PicklingError

PicklingError, _pickle.PicklingError, module=_pickle

5 _pickle.UnpicklingError

UnpicklingError, _pickle.UnpicklingError, module=_pickle
