pickle.load（）填充文本文件的EOFerror

Question

I have a small piece of code in my program that imports a dict from a text file
It gives me the following error:

Traceback (most recent call last):
  File "C:\Users\S.Latil\Desktop\Python\HomeWork Full\HomeWork\test.py", line 3, in <module>
    Lesson = pickle.load(Li)
EOFError

My code is:

import pickle

with open('LessonOut.txt', 'rb') as Li:
 Lesson = pickle.load(Li)

print(Lesson)

In the file LessonOut.txt i have this string:

€}q X   helloqX   worldqs.

I don't understand why it gives me this error, I haven't seen a fix in other threads.
What it should print is {'hello','world'}
If anyone could explain why this error occurs and how to fix it it would be great

Answer 1

I found the error to the problem actually, it's pretty simple.
What happened was that i copyed and pasted the content of a pickle output file into my txt and because pickle doesn't use only ascii characters it didn't copy properly. All i did was redump the dict onto the file and it worked.
Hope this helped someone.
