I am getting an interesting error while trying to use Unpickler.load(), here is the source code:

open(target, "a").close()
scores = {};
with open(target, "rb") as file:
    unpickler = pickle.Unpickler(file);
    scores = unpickler.load();
    if not isinstance(scores, dict):
        scores = {};

Here is the traceback:

Traceback (most recent call last):
File "G:pythonpenduuser_test.py", line 3, in <module>:
    save_user_points("Magix", 30);
File "G:pythonpenduuser.py", line 22, in save_user_points:
    scores = unpickler.load();
EOFError: Ran out of input

The file I am trying to read is empty. How can I avoid getting this error, and get an empty variable instead?

Simply put and clear. Thank you for sharing. Why do I get “Pickle – EOFError: Ran out of input” reading an empty file? and other issues with pty Python module was always my weak point 😁. I am just not quite sure it is the best method

Simply put and clear. Thank you for sharing. Why do I get “Pickle – EOFError: Ran out of input” reading an empty file? and other issues with traceback Python module was always my weak point 😁. Will use it in my bachelor thesis

test Python module is always a bit confusing 😭 Why do I get “Pickle – EOFError: Ran out of input” reading an empty file? is not the only problem I encountered. I just hope that will not emerge anymore
