(Pymongo) AttributeError: 'InsertManyResult' object has no attribute 'inserted_count'

I follow the manual https://api.mongodb.com/python/3.4.0/api/pymongo/results.html
and similar problem AttributeError: 'dict' object has no attribute 'is_active' (PyMongo And Flask) (not fit mine issue)
after successfully .insert_many or .insert_one,
the .inserted_count not working

• function main part I stock

if one_or_many_bool == True:
    x = mycol.insert_many(insert_values_json)
else:
    x = mycol.insert_one(insert_values_json)
return x

print(x)
print(x.inserted_count, "documents insert.")

• output:

<pymongo.results.InsertManyResult object at 0x0000017D1D256950>
Traceback (most recent call last):
  File "C:\Users\chuan\OneDrive\Desktop\10.17_connect_mongoD_練習\fake02.py", line 54, in <module>
    print(x.inserted_count, "documents inserted.")
AttributeError: 'InsertManyResult' object has no attribute 'inserted_count'

• the whole code(incase someone want to take a look):

# 1 means success 
return_status_str = { "ok" : 1 , "msg" : msg_fail_reason , "count" : number_of_insert_data}

print(type(return_status_str))

As the PyMongo doc described, InsertManyResult doesn't has the inserted_count attrbute. You can use len(result.inserted_ids) instead.
