With the development of data analysis, most companies' requirements for data analysts are no longer limited to tools such as Excel and SQL. In order to quickly process and visualize data, Python has become an essential skill for data analysis. As a programming language that is easy to get started with, it can not only automatically process large amounts of data, but also crawl data on web pages for reference and analyze the development of the industry.
Beginners to Python are indispensable for environment installation. This section mainly provides a tutorial on the installation steps of anaconda for Windows .
download:
The official website generally displays the latest installation packages. Students who use computers and mobile phones know that when using installation packages, they generally do not choose the latest version, because many new versions are not compatible with the libraries to be used, and various problems may occur when the project is running. puzzling question

Baidu Netdisk: Baidu Netdisk
Extraction code: sfjy
anaconda is a package manager (including a large number of powerful third-party libraries). It is mainly used to manage the environment and allocate corresponding environments to different Python projects.
Enter the official website to select the version. It is recommended to use the 2021.11 version. For 64-bit operating systems, choose 64, and for 32-bit operating systems, choose the second one (Baidu Netdisk stores the 2022.10 version)

After the windows installation is completed, you can find the Anaconda folder in the menu bar. Expand the file and open the jupyter notebook. The jupyter terminal will start. Do not close the black window!
At this time, a webpage will pop up. The files displayed on the webpage are the local locations selected by the red box. The webpage files use this location as the main directory.
The web page cannot pop up. It may be that the browser cannot start automatically. You can copy the content of the blue box in the jupyter terminal, manually open the browser, and paste it into the web page bar.
In order to facilitate subsequent use, you can also add jupyter to the desktop
To close Jupytrt Notebook, you only need to close the page (the written code is in the created folder and exists with the suffix ipynb).
Next, let’s learn python! During use, remember not to close the jupyter terminal.
