//迭代count次
for i in range(0,count):
//使用urllib打开url对应的html文件为html变量
html = urllib.request.urlopen(url, context=ctx).read()
//使用BeautifulSoup解释html为soup，类似ParseJSON，使其可以直接通过标签的条件进行查询
soup = BeautifulSoup(html, 'html.parser')
//获取soup中所有的a（超链接）标签的对象为tags数组
//a标签一般写法为<a href="www.******.com/******/***">等
tags=soup('a')
//获得tags中第pos个超链接标签对象的超链接url，且该url进入下个循环
url=tags[pos-1].get('href',None)
//打印url
print(url)
这段代码根据每个页面第pos个超链接指向的页面进行count次迭代，找到最终指向的网址。
例如页面a第pos个链接指向页面b，页面b指向c，页面c指向d
以a为起始循环count=3次会打印出b，c，d的url
P.S. 说清楚你不懂的是什么在问问题的时候很重要

装了python3.7 大包的时候显示python3不是内部或外部指令_course

关于Mac下python pip版本问题以及pycharm安装python第三方库失败问题_course
2020-01-18我的电脑是mac 10.15版本 目前有两个python： 1. 系统自带Python 2.7.16 2. 自己安装python Python 3.7.3 在终端查询pip版本，结果是2.7的那个： pip 19.3.1 from /Library/Python/2.7/site-packages/pip (python 2.7) 查询pip3，结果显示错误： xcrun: error: invalid active developer path (/Library/Developer/CommandLineTools), missing xcrun at: /Library/Developer/CommandLineTools/usr/bin/xcrun 好像问题就是在这里，我在终端用 pip install 安装python第三方库的时候总会有问题，提示pip版本过低，我想更新pip又会失败；或者根本无法安装。 然后我就选择从pycharm上搜索第三方库并安装，奇怪的是有的库可以成功安装，有的库安装失败并提示说pip版本过低，让我尝试从终端安装，可是从终端安装的话又会遇到之前的问题。 请问这个该怎么解决？
安装python 后启动不了python程序_course
2011-03-08安装python 后启动不了python程序，提示“由于应用程序配置不正确，应用程序未能启动。重新安装应用程序可能会纠正这个问题”。我重新安装后还是老错误。经过搜索，有人说是没用安装vc studio ，但是安装后仍旧不行。 <br />头一回遇到这错，难度要重装系统？ <br /><img src="/images/smiles/icon_redface.gif"/> <br/><strong>问题补充</strong><br/>谢谢楼上的两位。不是环境变量的问题，这点我可以肯定。 <br />我装的是visual C++ 2008 express。所以，肯定也不是runtime的问题。而且我把那几个dll都拷贝到system32下面去了，还是不行。我试过其他的几个版本了，还有那些集成的环境，都不行。在cmd窗口，切换到python目录运行python，提示无非运行指定的程序

python读取dat文件数据_course
2016-03-10dat文件中的数据已用IDL读取，可获取到3维数组，表示的是跨越一段时间的一个地理区域的植被信息； 现在，想要用python来读取同一个文件，识别成3维数组。 问题：用python具体怎样操作呢，能否提供具体的代码呢，尝试着可以之后再去理解。 跪求大神的帮助，万分期待与感谢。 总共就5个币，全给了哈！ 首先，非常感谢大家的回答，现对问题补充如下： 11.7GB 大小的dat数据文件，使用readline循环读出，却显示只有4行，而且显示乱码 ，判断了编码格式，结果如下：

如何指定uwsgi在启动时默认的python版本_course
2019-08-26最近用django写了个项目,用的是python3.6，想放在服务器上用uwsgi+nginx运行的，因为服务器默认的是python2.7，所以我在服务器上安装了python3并创建软连接，这是我的uwsgi的配置文件,名字叫uwsgi.ini：  我的项目在python2中运行不了，但是uwsgi启动时默认的是python2，所以我在配置文件中加了这样一句：plugin=python3 然后当我执行命令：uwsgi --ini uwsgi.ini时出现问题：  我也知道问题在这里， open（“./ python3_plugin.so”）：没有这样的文件或目录[core / utils.c line 3724] ！无法加载uWSGI插件：./ python3_plugin.so：无法打开共享对象文件：没有这样的文件或目录！ 但是我不知道创建这个文件之后我应该做什么？ 恳请大佬解答。
初学PYTHON，找不到模块_course
2009-11-15小弟我初学PYTHON，刚刚学到模块这一章，按教程提示操作，却找不到模块。 PYTHON版本为3.1.1 Final，安装在D:\Python31，于是我就在D:\Python31这个路径下新建了一个fibo.py文件，内容如下： [code="python"] # Fibonacci numbers module # 斐波那契数 模块 def fib(n): # write Fibonacci series up to n a, b = 0, 1 while b < n: print(b, end=' ') a, b = b, a+b def fib2(n): # return Fibonacci series up to n result = [] a, b = 0, 1 while b < n: result.append(b) a, b = b, a+b return result [/code] 然后我在IDLE（PYTHON GUI）下试图导入fibo模块，却提示找不到这个模块。用sys.path查看路径，也能找到PYTHON的路径啊。 >>> import sys >>> sys.path ['D:\\Python31\\Lib\\idlelib', 'C:\\Windows\\system32\\python31.zip', 'D:\\Python31\\DLLs', 'D:\\Python31\\lib', 'D:\\Python31\\lib\\plat-win', '[color=blue]D:\\Python31[/color]', 'D:\\Python31\\lib\\site-packages'] >>> import fibo Traceback (most recent call last): File "<pyshell#4>", line 1, in <module> import fibo ImportError: [color=red]No module named fibo[/color] >>> 是哪里出了问题吗？ 操作系统是WIN7正式旗舰版。会不会跟操作系统有关？

2014-03-26安装ubuntu12自带python2.7，由于安装其他软件需要python2.6，但是后来安装openstack和python2.6产生包依赖问题，于是把2.6相关的文件都删除了，重装了python2.7。之后仍提示depends on python (>= 2.7.1-0ubuntu2); however: Version of python on system is 2.6.5-0ubuntu1。之后运行sudo apt-get -f install修复后，然后安装openstack又出现python Package python is not installed。 求大神解救 ！！！！！
C/C++ 与 Python 的通信-- python高手指导哈_course
2015-10-08我在python中传递一个函数指针给C编写的dll, 在dll中保存回调函数指针，并且开启一个线程，间隔调用此回调函数，函数可以正常运行（函数里面就一条打印语句），但是没有进入python定义的函数体执行，而回调函数可以正常执行，看起来应该是重新开辟了一块内存，将python的这个回调函数进拷贝过去了。这是咋回事，如何解决？

150讲轻松搞定Python网络爬虫
2019-05-16【为什么学爬虫？】 1、爬虫入手容易，但是深入较难，如何写出高效率的爬虫，如何写出灵活性高可扩展的爬虫都是一项技术活。另外在爬虫过程中，经常容易遇到被反爬虫，比如字体反爬、IP识别、验证码等，如何层层攻克难点拿到想要的数据，这门课程，你都能学到！ 2、如果是作为一个其他行业的开发者，比如app开发，web开发，学习爬虫能让你加强对技术的认知，能够开发出更加安全的软件和网站 【课程设计】 一个完整的爬虫程序，无论大小，总体来说可以分成三个步骤，分别是： 网络请求：模拟浏览器的行为从网上抓取数据。 数据解析：将请求下来的数据进行过滤，提取我们想要的数据。 数据存储：将提取到的数据存储到硬盘或者内存中。比如用mysql数据库或者redis等。 那么本课程也是按照这几个步骤循序渐进的进行讲解，带领学生完整的掌握每个步骤的技术。另外，因为爬虫的多样性，在爬取的过程中可能会发生被反爬、效率低下等。因此我们又增加了两个章节用来提高爬虫程序的灵活性，分别是： 爬虫进阶：包括IP代理，多线程爬虫，图形验证码识别、JS加密解密、动态网页爬虫、字体反爬识别等。 Scrapy和分布式爬虫：Scrapy框架、Scrapy-redis组件、分布式爬虫等。 通过爬虫进阶的知识点我们能应付大量的反爬网站，而Scrapy框架作为一个专业的爬虫框架，使用他可以快速提高我们编写爬虫程序的效率和速度。另外如果一台机器不能满足你的需求，我们可以用分布式爬虫让多台机器帮助你快速爬取数据。 从基础爬虫到商业化应用爬虫，本套课程满足您的所有需求！ 【课程服务】 专属付费社群+每周三讨论会+1v1答疑
