pymongo find

pymongo的find()方法用于在MongoDB中查询数据。通过使用find()方法，可以返回一个迭代器，然后可以使用for循环逐条输出查询结果。例如，可以使用以下代码查询数据并输出结果：

import pymongo

client = pymongo.MongoClient(host='localhost', port=27017)
db = client.test
collection = db.students

result = collection.find()
for r in result:
    print(r)

这段代码会查询名为"students"的集合中的所有数据，并逐条输出结果。输出结果中包含每条数据的字段和对应的值。
