This article introduces the use of python to capture job search website information

This time, the information captured is the information after searching for "data analyst" on the Zhaopin recruitment website.

python Version: python3.5.

The main package I use is Beautifulsoup + Requests+csv

In addition, I also grabbed a brief description of the recruitment content.

After the file was output to a csv file, I found that there were some garbled characters when opening it with excel, but there was no problem when opening it with file software (such as notepad++).

In order to display it correctly when opened in Excel, I used pandas to convert the following and added the column names. After the conversion is completed, it can be displayed correctly. Regarding conversion with pandas, you can refer to my blog:

Since there are many descriptions of the recruitment content, finally save the csv file as an excel file and adjust the format for easy viewing.

The final effect is as follows: Use python to grab job search website information

The implementation code is as follows: The code for information crawling is as follows:
