在Python中酸洗錯誤：io.UnsupportedOperation：讀

Question

我想學習如何在並保存一個對象在python中。但是，當我使用下面的sample code時，我得到以下錯誤：io.UnsupportedOperation: read其追溯到favorite_color = pickle.load(f_myfile)。我找不到這個特定錯誤的好解釋。我做錯了什麼，我該如何糾正？

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() 

Answer 1

變化：

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

到：

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

，你可以看到字典的obj你醃。
