I am a novice, and I am here to ask the experts for advice. . . To save an instance of a class in pickle, do you use pickle.dump() to save the instantiated class into a pkl file after instantiating the class?
For example:
class zxc():
x=1b=zxc()
with open("zxc.pkl", "wb") as f:
pickle.dump(b, f)If this is the case, if you need to call this instantiated class to others, should you give the entire class to others? Or can I just give the file?

pickle.load Read the English documentation of this API in detail
And pickle the entire module’s documentation
Then the problem can be solved
When pickle.load is executed, Python will try to import the module file containing class zxc. If it cannot be imported, an exception will be thrown. A similar error will occur if the class and module are renamed or the module is moved to another directory.
So, not only do you need to give the relevant module files to others, but you also need to ensure the consistency of the relative directories.
