List of mixed data types to bytes

[scidam]

You can standard pickle module, e.g.

import pickle
from io import BytesIO

bs = BytesIO()

class MyClass:
    ...

mm = MyClass()
# lets store mm as a bytestring

pickle.dump(mm, bs)
bs.seek(0) # move to the begining of the File-like object
print(bs.read()) # this bytesting represents the instance of MyClass (mm)

# you can restore the object, e.g.
bb.seek(0)
restored = pickle.load(bs)

If objects are really complex, you could try to customize __setstate__ and __getstate__ methods (see official docs on pickle module for details).
