零基础写python爬虫之抓取百度贴吧代码分享
这里就不给大家废话了,直接上代码,代码的解释都在注释里面,看不懂的也别来问我,好好学学基础知识去!
代码如下:
# -*- coding: utf-8 -*-
#---------------------------------------
# 程序:百度贴吧爬虫
# 版本:0.1
# 作者:why
# 日期:2013-05-14
# 语言:Python 2.7
# 操作:输入带分页的地址,去掉最后面的数字,设置一下起始页数和终点页数。
# 功能:下载对应页码内的所有页面并存储为html文件。
#---------------------------------------
import string, urllib2
#定义百度函数
def baidu_tieba(url,begin_page,end_page):
for i in range(begin_page, end_page+1):
sName = string.zfill(i,5) + '.html'#自动填充成六位的文件名
print '正在下载第' + str(i) + '个网页,并将其存储为' + sName + '......'
f = open(sName,'w+')
m = urllib2.urlopen(url + str(i)).read()
f.write(m)
f.close()
#-------- 在这里输入参数 ------------------
# 这个是山东大学的百度贴吧中某一个帖子的地址
#bdurl = 'http://tieba.baidu.com/p/2296017831?pn='
#iPostBegin = 1
#iPostEnd = 10
bdurl = str(raw_input(u'请输入贴吧的地址,去掉pn=后面的数字:\n'))
begin_page = int(raw_input(u'请输入开始的页数:\n'))
end_page = int(raw_input(u'请输入终点的页数:\n'))
#-------- 在这里输入参数 ------------------
#调用
baidu_tieba(bdurl,begin_page,end_page)
以上就是python抓取百度贴吧的一段简单的代码,非常的实用吧,各位可以自行扩展下。

VS Code extensions pose malicious risks, such as hiding malicious code, exploiting vulnerabilities, and masturbating as legitimate extensions. Methods to identify malicious extensions include: checking publishers, reading comments, checking code, and installing with caution. Security measures also include: security awareness, good habits, regular updates and antivirus software.

VS Code can run on Windows 8, but the experience may not be great. First make sure the system has been updated to the latest patch, then download the VS Code installation package that matches the system architecture and install it as prompted. After installation, be aware that some extensions may be incompatible with Windows 8 and need to look for alternative extensions or use newer Windows systems in a virtual machine. Install the necessary extensions to check whether they work properly. Although VS Code is feasible on Windows 8, it is recommended to upgrade to a newer Windows system for a better development experience and security.

In VS Code, you can run the program in the terminal through the following steps: Prepare the code and open the integrated terminal to ensure that the code directory is consistent with the terminal working directory. Select the run command according to the programming language (such as Python's python your_file_name.py) to check whether it runs successfully and resolve errors. Use the debugger to improve debugging efficiency.

VS Code can be used to write Python and provides many features that make it an ideal tool for developing Python applications. It allows users to: install Python extensions to get functions such as code completion, syntax highlighting, and debugging. Use the debugger to track code step by step, find and fix errors. Integrate Git for version control. Use code formatting tools to maintain code consistency. Use the Linting tool to spot potential problems ahead of time.

PHP is suitable for web development and rapid prototyping, and Python is suitable for data science and machine learning. 1.PHP is used for dynamic web development, with simple syntax and suitable for rapid development. 2. Python has concise syntax, is suitable for multiple fields, and has a strong library ecosystem.

VS Code is available on Mac. It has powerful extensions, Git integration, terminal and debugger, and also offers a wealth of setup options. However, for particularly large projects or highly professional development, VS Code may have performance or functional limitations.

VS Code not only can run Python, but also provides powerful functions, including: automatically identifying Python files after installing Python extensions, providing functions such as code completion, syntax highlighting, and debugging. Relying on the installed Python environment, extensions act as bridge connection editing and Python environment. The debugging functions include setting breakpoints, step-by-step debugging, viewing variable values, and improving debugging efficiency. The integrated terminal supports running complex commands such as unit testing and package management. Supports extended configuration and enhances features such as code formatting, analysis and version control.

Golang is more suitable for high concurrency tasks, while Python has more advantages in flexibility. 1.Golang efficiently handles concurrency through goroutine and channel. 2. Python relies on threading and asyncio, which is affected by GIL, but provides multiple concurrency methods. The choice should be based on specific needs.
