这样，在后续代码中， .py 和 .ipynb源代码一致，无需为在Jupyter Notebook中运行而进行修改。在Jupyter Notebook中，运行Python源代码非常方便，但是如何模拟命令行方式运行时的输入参数呢？如果直接使用sys.argv会出现错误。argv[1]为 test.txt。因此，解决方案就是对。

Python开发简单爬虫徐老师的课程“Python开发简单爬虫”（链接：https://www.imooc.com/learn/563）思路清晰，步骤详细，讲解细致，是非常好的Python爬虫开发入门课程。美中不足的是随着时间推移，课程中的有些库更新了，百度百科词条的url格式也变了，如果完全按照课程的内容开发代码是不能正常工作的。下面的代码是经过修改后的代码，而且为便于初学者阅读，添加了详细注释。共5个源代码文件：spider_main.py, url_manager.py, html_dow

使用Python写文件的时候，或者将网络数据流写入到本地文件的时候，大部分情况下会遇到：UnicodeEncodeError: 'gbk' codec can't encode character '\xa0' in position ... 这个问题。 网络上有很多类似的文件讲述如何解决这个问题，但是无非就是encode，decode相关的，这是导致该问题出现的真正原因吗？不是的。 很多时候，我们使用了decode和encode，试遍了各种编码，utf8，utf-8,gbk,gb2312等等，该有的编码都

Python包：包即文件夹，包含__init__.py文件（标识当前文件夹是一个包） 是一个分层次的目录结构，定义了一个由模块及子包和子包下的子包等组成的Pythone的应用环境 例如：test.py package-runoob |----__init__.py |----runoob1.p...
