[Python] Why do I get "Pickle - EOFError: Ran out of input" reading an empty file?

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:\python\pendu\user_test.py", line 3, in <module>:
save_user_points("Magix", 30);
File "G:\python\pendu\user.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?
