在 Python 中使用 PyMongo 处理 MongoDB 查询结果

pip install pymongo

from pymongo import MongoClient

client = MongoClient('mongodb://localhost:27017/')

db = client['mydatabase']

collection = db['customers']

# 查询所有记录
results = collection.find()

# 查询指定记录
result = collection.find_one({'name': 'pidancode.com'})

collection = db['customers']
results = collection.find()

for result in results:
    print(result)

collection = db['customers']
data = {'name': 'pidancode.com', 'country': 'China'}
collection.insert_one(data)

collection = db['customers']
collection.update_one({'name': 'pidancode.com'}, {'$set': {'country': 'USA'}})

collection = db['customers']
collection.delete_one({'name': 'pidancode.com'})
