如何从Python文件中解脱一系列对象? [英] How do I unpickle a series of objects from a file in Python?

问题描述

我已在附加模式下将对象腌制到文件中，但它仅读取单个对象.这是代码.我不知道我在做什么错.

I have pickled objects to a file in append mode but it only reads a single object. Here's the code. I don't know what I am doing wrong.

with open('notes.pkl', 'ab') as fileObject:                #append
    pickle.dump(obj, fileObject, pickle.HIGHEST_PROTOCOL)

with open('notes.pkl', 'rb') as input:                     #read
    obj= pickle.load(input)
    //perform tasks for each obj unpickled from the file

推荐答案

您需要重复调​​用pickle.load直到遇到文件结尾.

You need to call pickle.load repeatedly until you hit end-of-file.
