A period of time has been studying how to use Python to crawl search engine results, in the implementation of the process encountered a lot of problems, I have to record the problems I encountered, I hope to encounter the same problem of children's shoes to avoid detours. 1. Selection of search engines Choosing a good search engine means you can get more accurate search results. There are four types of search engines I've used: Google, Bing, Baidu, Yahoo! As a programmer, I prefer Google. But w

Advanced Usage 2: Specify legend that display a few curves: for example, you have 25 curves, you want to display LEGENDH = Plot (data) 1,6,11,16,21, Legend (H ([1 6 11 16 21], ' 1, ' 6 ', ' 11 ', ' 16 ', ' 21 '); Advanced usage 3:legend Horizontal HL = Legend

DifferenceGET is simpler and faster than POST, and can be used in most cases.However, use the POST request in the following cases: Unable to use cache file (update file or database on server) Send a large amount of data to the server (POST has no data volume limit) Post is more stable and more reliable than GET when sending user input with unknown characters GET RequestGenerally used for information acquisition, using the URL to pass p

The Get method requires the server to place the URL-positioned resource in the data portion of the response message, which is sent back to the client. When using the Get method, the request parameter and the corresponding value are appended to the URL, using a question mark ("?" ) represents the end of the URL and the start of the request parameter, which is limited by the length of the pass para

Loops are often used in shell programming, and the commonly used loops are for and while loops. While loops read files by default in rows, and for loops read file-splitting files with spaces, this article combines some examples of current web usage and differences. First, common grammar 1, for Loop The syntax structure used for a For loop is as follows: For variable in SEQ stringFor variable in ' command 'For variable in "$@" or "$*"for ((assignment; condition; Operation statement) 2, while
