Python: Errors saving and loading objects with pickle module
- by Peterstone
Hi, I am trying to load and save objects with this piece of code I get it from a question I asked a week ago: Python: saving and loading objects and using pickle.
The piece of code is this:
class Fruits: pass
banana = Fruits()
banana.color = 'yellow'
banana.value = 30
import pickle
filehandler = open("Fruits.obj","wb")
pickle.dump(banana,filehandler)
filehandler.close()
file = open("Fruits.obj",'rb')
object_file = pickle.load(file)
file.close()
print(object_file.color, object_file.value, sep=', ')
At a first glance the piece of code works well, getting load and see the 'color' and 'value' of the saved object.
But, what I pursuit is to close a session, open a new one and load what I save in a past session. I close the session after putting the line filehandler.close() and I open a new one and I put the rest of your code, then after putting object_file = pickle.load(file) I get this error:
Traceback (most recent call last):
File "<pyshell#5>", line 1, in <module>
object_file = pickle.load(file)
File "C:\Python31\lib\pickle.py", line 1365, in load
encoding=encoding, errors=errors).load()
AttributeError: 'module' object has no attribute 'Fruits'
Can anyone explain me what this error message means and telling me how to solve this problem?
Thank so much and happy new year!!
