您不需要查找循環(huán)，只需使用它iterrows()來獲取數(shù)據(jù)并UpdateOne執(zhí)行更新插入。
from pymongo import MongoClient, UpdateOne
import pandas as pd
db = MongoClient()['mydatabase']
data = [['ec299fa905e038dec3c8e93', 'Kederi Yusof· basikal salah Najib.Tayar pa...', 1],
['ec49452bfcd4786382fe21f', 'Serindik.com·2 laaa mimpi UMNO.... XPM7 pul...', 0]]
df = pd.DataFrame(data, columns=['_id', 'text', 'sentiment'])
updates = []
for _, row in df.iterrows():
updates.append(UpdateOne({'_id': row.get('_id')}, {'$set': {'sentiment': row.get('sentiment')}}, upsert=True))
db.twitter.bulk_write(updates)
