1. The language is concise and easy to learn
The design philosophy of Python language is "elegant", "clear" and "simple". This makes Python an easy-to-read and easy-to-write language, and even beginners can quickly get started.
2. Rich libraries and tools
Python has numerous third-party libraries and tools for processing various data formats, parsing web pages, sending HTTP requests, etc. These tools make crawler writing easier and more efficient.
3. Cross-platform
Python can run on multiple operating systems, including Windows, Linux, and Mac OS. This makes Python a very flexible programming language that can easily develop and deploy crawlers on different platforms.
4. Strong community support
Python has a large developer community that provides a lot of resources and support. This makes it possible to quickly find solutions when problems arise, and it is easy to communicate and share experiences with others.
Next, let’s explore the advantages of using proxy IP for crawlers.
1. Hide your real IP address
When using a proxy IP, the crawler's request will first be sent to the proxy server, which will then send the request to the target website. In this way, the target website can only see the IP address of the proxy server, but cannot know the real IP address of the crawler, thus protecting the crawler's privacy.
2. Break through limitations
Some websites will limit requests from specific IP addresses, or frequency limit requests from the same IP address. Using a proxy IP can avoid this, because each proxy IP has its own independent IP address and can simulate requests from different regions.
3. Accelerate access speed
Proxy servers are usually located in high-speed network environments and can cache web page content, thereby reducing network latency and data transmission time. This allows crawlers using proxy IPs to access target websites faster and improve data crawling efficiency.
4. Better response to network fluctuations and disconnections
Using proxy IP allows the crawler to continue running when the target website is inaccessible or there is network fluctuation. When the proxy server fails, the crawler can automatically switch to other available proxy servers to ensure the stability and continuity of data crawling.
In summary, Python, as the main language of choice for crawlers, has the advantages of being concise and easy to learn, rich libraries and tools, cross-platform, and strong community support. At the same time, using proxy IP can bring advantages to crawlers such as hiding real IP addresses, breaking restrictions, accelerating access speed, and better coping with network fluctuations and disconnections. Therefore, it is a common practice to choose Python language and use proxy IP when writing crawlers.
