Charles,

by your own admission, you deleted your pkl file,

And your code doesn't write that pkl file (pickle.dumps(...) doesn't write a file it creates a new string and at no point will it write to the file :

What you need is this :

        import pickle
        number=2
        my_pickled_object=pickle.dumps(number)
        with open('file.pkl', 'w') as file:
                file.write(my_pickled_object)
        print("this is my pickled object",{my_pickled_object},)

        del number # you can do this if you really want to test pickle.

        with open('file.pkl', 'r') as file:
                number=pickle.load(file)

        my_unpickled_object=pickle.loads(my_pickled_object)
        print("this is my unpickled object",{my_unpickled_object},)

Note :  that the whole point of the pickle format is that you don't need to open and write/read files in binary format.

Hello,
I am experincing problems with the pickle moducle
the folowing code was working before,

import pickle
number=2
my_pickeld_object=pickle.dumps(number)
print("this is my pickled object",{my_pickeld_object},)
with open('file.pkl', 'rb') as file:
     number=pickle.load(file)
my_unpickeled_object=pickle.loads(my_pickeld_object)
print("this is my unpickeled object",{my_unpickeled_object},)

but now i get error

Traceback (most recent call last):
   File "C:\Users\lukwi\Desktop\python\tester2.py", line 5, in <module>
     with open('file.pkl', 'rb') as file:
FileNotFoundError: [Errno 2] No such file or directory: 'file.pkl'

im get this problem after this,
a .pkl came into my Python script files
i though this could be a spare file made from python becauce i was doing this 
first,

import pickle
number=2
my_pickeld_object=pickle.dumps(number)
print("this is my pickled object",{my_pickeld_object},)
with open('file.pkl', 'rb') as file:
     number=pickle.load(file)

so i stupidly deleted the file

do you know how to fix this?
i reinstalled it but it didn't work
this is on widnows and on version 3.11.3 on python

thank you
