BeautifulSoup，soup() 和soup.findAll() 的区别？
[英]BeautifulSoup, difference between soup() and soup.findAll()?
问题描述
I'm confused about the difference between soup('tag_name') and soup.find_all('tag_name') .
我对soup('tag_name') soup.find_all('tag_name') soup('tag_name')和soup.find_all('tag_name') soup('tag_name')之间的区别感到困惑。 Here is an example with a short bit of html:这是一个带有一小段 html 的示例：
from bs4 import BeautifulSoup
string = """
<html><body><div class="MsoNormal">
<span style='font-family: "Times New Roman","serif"; font-size: 12.0pt;
line-height: 107%;'> Some text <o:p></o:p></span></div></body></html>
"""
soup = BeautifulSoup(string)
if soup('span') == soup.find_all('span'):
print('No difference')
This example is small, but I've tested much longer strings and found no difference between the two.这个例子很小，但我测试了更长的字符串，发现两者之间没有区别。 I thought it might be new as of bs4 but all I could see in the documentation is that findAll became find_all .我认为从bs4它可能是新的，但我在文档中看到的只是findAll变成了find_all 。 Are these two methods the same?这两种方法一样吗？ Is the first one actually a method?第一个实际上是一种方法吗？ When will they give different results?他们什么时候会给出不同的结果？

No, there is no difference between the two.不，两者之间没有区别。
From the documentation : " If you treat the BeautifulSoup object or a Tag object as though it were a function, then it's the same as calling find_all() on that object. "来自文档：“如果您将 BeautifulSoup 对象或 Tag 对象视为一个函数，那么它与在该对象上调用 find_all() 相同。 ”
