Firestore updates using python api are not persisting

Question

I have the following code.

from firebase_admin import firestore

db = firestore.client()
collection = db.collection('word_lists')
word_list = collection.get()

for item in word_list:
    item_dict = item.to_dict()
    print item_dict['next_practice_date']
    item.reference.update({'next_practice_date': 0.0})

When I run the code the first time everything is fine, no errors. The second time I run it I expect all the prints to print 0.0 but instead many print None, particularly the ones at the end. What is going on?

I did not find the solution to the problem but instead switched from firebase_admin import firestore

to from google.cloud import firestore and everything works well now.

from firebase_admin import firestore

db = firestore.client()
collection = db.collection('word_lists')
word_list = collection.get()

if not word_list.exists(): return
for item in word_list:
    item_dict = item.to_dict()
    print(item_dict['next_practice_date'])
    item.reference.update({'next_practice_date': 0.0})
