Change the encoding method of the python output stream

I recently played BeautifulSoup and wanted to crawl some of my favorite data. In this case, BeautifulSoup converts & nbsp; To '\ xa0' by default, as a result, gbk cannot output the conversion to gbk, but the default encoding method of file output in my system is gbk, so I want to output the file, you need to change the file encoding method. For example, in python 2.4, you can use f1_open('out.html ', 'w', and 'utf-8') to implement this, but what about the new version? After checking for a long time, we finally implemented it. We can use the codecs f‑code.open('out.html ', 'w', 'utf-8') class to print> f, data or f. write (data) is attached with the method to change the encoding method of the standard output stream import codecs, sys old = sys. stdout sys. stdout = codecs. lookup ('iso8859-1') [-1] (sys. stdout)
