import pymongo

client = pymongo.MongoClient()
person = client.person
student = person.student
result = student.find()
for r in result:
    print(r)

print(result.next())
print(result.next())
print(result.next())

result = student.find({"name": "張無忌"})
result = student.find().sort("age", 1)
result = student.find().sort("age", pymongo.DESCENDING)
result = student.find().limit(3).skip(2)
for r in result:
    print(r)

# 查詢數量
result = student.estimated_document_count()
# 有條件查詢數量
result = student.count_documents({'name': "張無忌"})
print(result)

data = {"name": "黃月英", "age": "19"}
data = [{"name": "小喬"}, {"name": "大喬"}]
result = student.insert_many(data)

result = student.delete_one(data)

data = {"name": "小喬"}
result = student.find_one(data)
# print(result)
result['age'] = '18'
student.update_one(data, {"$set": result})

結果：
