我有一个Python库存更新脚本,该脚本每晚运行一次,从网站上提取库存。我最近开始遇到问题,经过进一步调查发现,当我通过Web浏览器(查看源代码)查看源内容时,它看起来很正常。但是,当我使用python将其打印到控制台时,它看起来很奇怪(并且正在破坏脚本)。想知道是否有人看到过这样的东西或知道是什么原因造成的?

网络浏览器显示以下内容(已编辑的网址):

<ul class='vnav vnav__subnav vnav--level2'>

</li></ul>

但是控制台中的Python print()显示以下内容(已编辑的URL):

在网络浏览器中,内容类型为“ text / html”,编码为“ ISO-8859-1”,但通过Python打印时显示为“ UTF-8”。另外,在Python控制台print()上,html的其余全部与所有空格和字符一起出现,除了结尾处的右边,它恢复了正常(除了看起来有2个标记,这是一个不同的问题):

 /   b   o   d   y   &gt;   
   /   h   t   m   l   &gt;   
</a></li></ul></div></nav></body></html>

最后,如果我尝试使用UTF-8而不是ISO-8859-1进行解码,则会出现以下错误:

UnicodeDecodeError: 'utf8' codec can't decode byte 0xe9 in position 74396: invalid continuation byte

答案 0 :(得分:0)

没关系,想通了。

最重要的提示:在不同的VirtualEnvs中工作时,请始终确保您的python版本是相同的。本来我没有检查,但是当我来回跳来跳去时,才决定进行验证。我假设正在使用的python版本没有使用。一旦我进行了切换...是的!更好。
