如何在 Python 中使用 PyMongo 更新 MongoDB 文档

import pymongo

# 连接 MongoDB 数据库
client = pymongo.MongoClient("mongodb://localhost:27017/")
db = client["mydatabase"]
collection = db["customers"]

# 更新文档
query = { "name": "John" }
new_values = { "$set": { "address": "pidancode.com" } }
collection.update_one(query, new_values)

# 输出更新后的文档
for x in collection.find():
  print(x)

# 更新多个文档
query = { "address": { "$regex": "^S" } }
new_values = { "$set": { "address": "皮蛋编程" } }
result = collection.update_many(query, new_values)
print(result.modified_count, "文档已更新")

# 输出更新后的文档
for x in collection.find():
  print(x)
