1. It can help individuals and enterprises to make future plans and provide users with better experience. So data collection is a very important task.
It's a lot of complicated data. When distributed on different websites, relying on people to collect crawling is not practical, too slow, not in line with the current work efficiency.
2. Python crawlers are required to crawl data on the network 24 hours a day without interruption. In this way, high-frequency access to the data of the target website will trigger the protection of the server and restrict the network IP address of the crawler, which is also known as IP packet processing.
A proxy IP is like a mask used to hide the real IP address. But this does not mean that the proxy IP is fake and does not exist. In fact, instead, the proxy'S IP address is a real online IP address. Therefore, real IP can have problems, proxy IP can also occur, such as: network latency, disconnection, etc.; So, we need an alternate IP address to replace it, because crawlers often have a lot of data to crawl and need a lot of alternate IP addresses.
