Adding new values with same keys to existing document in Firestore firebase without overwriting

I am trying to add data to the Firestore database without overwriting it. The data is in the format written below and has numerous other "Question" in the same format and I want to add this to just one document.

{
    "Question": String,
    "Answer": String,
}

The same question has been asked here but it covers it in java and not in python. I have tried updating it and setting it but it has only been overwriting it.
Note that all of my Questions are elements in a list in this format:

['{\n "Question": String,\n "Answer":String \n}, ...]

What I am currently doing in my code is going through the array and performing the code below:

doc_ref = db.collection(u"Questions").document(u"ques")
doc_ref.update(questionsAnswers)

but this only leaves me with the last question added to the database.

Use the update method to change the contents of an existing document as shown in the documentation.

city_ref = db.collection(u'your-collection').document(u'your-document')
city_ref.update({u'your-field': u'your-field-value'})

I suggest also using the API documentation.
