Python中的错误腌制:io.UnsupportedOperation:已读取 [英] Error Pickling in Python: io.UnsupportedOperation: read

问题描述

我正在尝试学习如何pickle并在python中保存对象.但是，当我在下面使用示例代码时，出现以下错误:io.UnsupportedOperation: read追​​溯到favorite_color = pickle.load(f_myfile).对于此特定错误，我找不到很好的解释.我在做什么错了，我该如何纠正?

I am trying to learn how to pickle and save an object in python. However, when I use the sample code below I get the following error: io.UnsupportedOperation: read which traces back to favorite_color = pickle.load(f_myfile). I cannot find a good explanation of this particular error. What am I doing wrong and how do I correct it?

import pickle  # or import cPickle as pickle

# Create dictionary, list, etc.
favorite_color = { "lion": "yellow", "kitty": "red" }

# Write to file
f_myfile = open('myfile.pickle', 'wb')
pickle.dump(favorite_color, f_myfile)
f_myfile.close()

# Read from file
f_myfile = open('myfile.pickle', 'wb')
favorite_color = pickle.load(f_myfile)  # variables come out in the order you put them in
f_myfile.close()

推荐答案

更改:

# Read from file 
f_myfile = open('myfile.pickle', 'wb')

收件人:

f_myfile = open('myfile.pickle', 'rb')

，您可以看到您腌制的字典obj.

and you can see the dict obj you've pickled.
