version of Python needed to read the pickle produced. The *file* argument must have a write() method that accepts a single bytes argument. It can thus be a file object opened for binary writing, an io.BytesIO instance, or any other custom object that meets this interface. If *fix_impor...
pickle 模块提供了以下函数对: dumps(object) 返回一个字符串,它包含一个 pickle 格式的对象; loads(string) 返回包含在 pickle 字符串中的对象; dump(object, file) 将对象写到文件,这个文件可以是实际的物理文件,但也可以是任何类似于文件的对象,这个对象具有 write() 方法,可以接受单个的字符串参数; load(fil...
pickle.load(file,*,fix_imports=True,encoding="ASCII",errors="strict"):从file对象文件读取pickled表示并且返回重构的目标层次 pickle.loads(bytes_object,*,fix_imports=True,encoding="ASCII",errors="strict"):从bytes_object读取一个pickled目标层次,返回重构的目标层次(object hierarchy)...

python的pickle是用来序列化对象很方便的工具,但是pickle对传入对象的要求是不能是内部类,也不能是lambda函数。 比如尝试pickle这个内部类: 结果会报错AttributeError: Can't pickle local object。 这个问题可以用第三方库dill来解决: (https://pypi.org/project/dill/) ...
