update data set after extracting features from face in python using pickle

I am new in python and following this article https://www.mygreatlearning.com/blog/face-recognition/#whatsopencv to extract features from face. After trying it, I realise that I do looping inside directory Images for each image and then save it inside face_enc:

datas = {"encodings": knownEncodings, "names": knownNames}  f = open("face_enc", "wb")  f.write(pickle.dumps(datas))  f.close()  

So, thing that makes me confused is, let's say that I have 50 images inside Images directory then I add another 100 images (just for example), so I will do looping from the start (1-150 images) and then save it in face_enc. Is there a way to update data inside face_enc without saving it from the start to saving time?
