How to set value with Beautiful Soup in some element if I know id of that HTML element or class ? For example I have
< td id ="test"></td >
并且我想设置文本还原...之类的
and I want to set text RESTORE... like
< td id ="test"> RESTORE ...</td> .

使用 find()搜索 id = test 查找要修改的标签.然后:
Find the tag you want to modify using a find() search for id=test. Then:
修改.string
如果您设置标签的.string属性，则标签内容将替换为您提供的字符串:
If you set a tag’s .string attribute, the tag’s contents are replaced with the string you give:
markup = '<a href="http://example.com/">I linked to <i>example.com</i></a>'
soup = BeautifulSoup(markup)
tag = soup.a
tag.string = "New link text."
tag
# <a href="http://example.com/">New link text.</a>
请注意:如果该标签包含其他标签，则它们及其所有内容将被销毁.
Be careful: if the tag contained other tags, they and all their contents will be destroyed.
