calculation results are as follows: It is important to note that the first month's ratio of the previous period value is empty (that is, January 2011). A4=a3.sort (m)This code will be A3 by month, year, in order to calculate the same time ratio. The complete code should be: =a3.sort (m,y), because A3 is originally sorted by year, so you can achieve the goal by the month sort, namely A3.sort (m), so the performance is also high. Some of the results are as follows: A5=a4.derive (if (m==m[-1],ma

Generally, the performance of a single crawler is limited, and a sufficient number of related webpages cannot be crawled within a reasonable time range. Therefore, in practice, a distributed crawler is generally designed to allow each crawler node to crawl a website close to it, and then integrate the structure to the user. Distributed Technology Applies to web crawlers, which not only reduces operation costs, but also greatly improves crawler performance. Especially in today's rapid development
