Ubuntu,安装了MongoDB和Python之后,Phython如何访问MongoDB数据库
Python是很简单的编程语言,开发的代码可读性非常好。
这篇文章,通过称为PyMongo driver的Python驱动和MongoDB一起开发简单简洁功能强大的代码。
安装PyMongo Driver
开始写python代码访问MongoDB数据库之前,我们首先需要安装PyMongo driver。
假设你已经安装了Python2.7或更高版本。Python的安装从上下载tar文件的安装介质
安装PyMongo driver的步骤如下:
步骤1:
下载Python相应版本的安装工具 。比如,我从
#using-setuptools-and-easyinstall下载了
setuptools-0.6c11-py2.7.egg
步骤2:
执行下载的介质
步骤3:
安装PyMongo模块:
好了!测试一下,在Python shell中,输入:
import pymongo返回光标>>,,就成功了。
更进一步,插入数据到数据库中,然后检索一下。记住MongoDB中,如果检索的数据库不存在,MongoDB会自动创建一个数据库,下面以mytestdeb为例测试一下。
Python shell中输入以下:
from pymongo import Connection c = Connection(); db = C.mytestdb collection = db.items item = {“Title”: “Test Data”, “Value1”:”1”, “Value2”:”2”} collection.insert(item) collection.find_one()执行最后一行的结果是:
{u'_id': ObjectId('4d432adc1d41c85d8a000000'), u'Value1': u'1', u'Value2': u'2', u'Title': u'Test Data'}

PHP is mainly procedural programming, but also supports object-oriented programming (OOP); Python supports a variety of paradigms, including OOP, functional and procedural programming. PHP is suitable for web development, and Python is suitable for a variety of applications such as data analysis and machine learning.

PHP is suitable for web development and rapid prototyping, and Python is suitable for data science and machine learning. 1.PHP is used for dynamic web development, with simple syntax and suitable for rapid development. 2. Python has concise syntax, is suitable for multiple fields, and has a strong library ecosystem.

When developing an e-commerce website, I encountered a difficult problem: how to provide users with personalized product recommendations. Initially, I tried some simple recommendation algorithms, but the results were not ideal, and user satisfaction was also affected. In order to improve the accuracy and efficiency of the recommendation system, I decided to adopt a more professional solution. Finally, I installed andres-montanez/recommendations-bundle through Composer, which not only solved my problem, but also greatly improved the performance of the recommendation system. You can learn composer through the following address:

To run Python code in Sublime Text, you need to install the Python plug-in first, then create a .py file and write the code, and finally press Ctrl B to run the code, and the output will be displayed in the console.

PHP originated in 1994 and was developed by RasmusLerdorf. It was originally used to track website visitors and gradually evolved into a server-side scripting language and was widely used in web development. Python was developed by Guidovan Rossum in the late 1980s and was first released in 1991. It emphasizes code readability and simplicity, and is suitable for scientific computing, data analysis and other fields.

Golang is better than Python in terms of performance and scalability. 1) Golang's compilation-type characteristics and efficient concurrency model make it perform well in high concurrency scenarios. 2) Python, as an interpreted language, executes slowly, but can optimize performance through tools such as Cython.

Running Python code in Notepad requires the Python executable and NppExec plug-in to be installed. After installing Python and adding PATH to it, configure the command "python" and the parameter "{CURRENT_DIRECTORY}{FILE_NAME}" in the NppExec plug-in to run Python code in Notepad through the shortcut key "F6".

Python is easier to learn and use, while C is more powerful but complex. 1. Python syntax is concise and suitable for beginners. Dynamic typing and automatic memory management make it easy to use, but may cause runtime errors. 2.C provides low-level control and advanced features, suitable for high-performance applications, but has a high learning threshold and requires manual memory and type safety management.
