Getting width/attributes out of a tag in Beautifulsoup instead of text - beautifulsoup

Question

So the beautifulsoup documentation I can find talks about finding a specific tag using id, class etc... But it doesn't talk about how to extract data from within the tag rather than what it surrounds.
My issue:
<img src=yellowbar.png width=63.94 height=10><img src=redbar.png width=36.0632181423 height=10><br />
Power:</b> 1480 / 1480<br />
<img src=yellowbar.png width=100 height=10><img src=redbar.png width=0 height=10><br />
I have this HTML. There are around a total of 20 tags on the page, of which 3 have src=yellowbar.png
my goal is, to select the second one, and get the width back. So I am guessing it would go:
Find tags -> find src=yellowbar.png -> select second one -> print width back.
How would I go about this?
So far I've managed to print a list of all tags.
soup = BeautifulSoup(element, "lxml")
tag = soup.find_all('img')
print(tag)
which returns
[<img height="10" src="yellowbar.png" width="77"/>, <img height="10" src="redbar.png" width="0"/>]

If I could understand your question then this should solve your issue.
from bs4 import BeautifulSoup
content = """
<img src=yellowbar.png width=63.94 height=10><img src=redbar.png width=36.0632181423 height=10><br />
Power:</b> 1480 / 1480<br />
<img src=yellowbar.png width=100 height=10><img src=redbar.png width=0 height=10><br />
"""
soup = BeautifulSoup(content,"lxml")
for tags in soup.find_all("img",{"src":"yellowbar.png"}): #use the attributes as well to specify the item you look for
print(tags['width']) #access the value using attribute
Output:
63.94
100
