Children & Parents attributes of BeautifulSoup

BeautifulSoup Basics
We can extract the parent tags or child tags by using children and parents attributes. To understand this let us create a string with structured parent and child tags.
content = """<h2>List of web programming languages</h2>
<UL>
<li>PHP</li>
<li>Python</li>
<li>JavaScript</li>
</UL>"""

from bs4 import BeautifulSoup
soup = BeautifulSoup(content, 'html.parser')
Now our soup is ready, we will use this to get child nodes. By using this method we will get a list and we can use for loop to iterate through all the elements.
for child in soup.ul.children:
    print(child)
    print(child.string)
Output is here ( part only )
<li>PHP</li>
PHP

<li>Python</li>
Python

Collecting the Parent Tags

By using parents method we can get all the parent tags. This will return one level up till it reaches the final node. To our above code we will add one more tag <body> and apply the parents method.
content = """<body><h2>List of web programming languages</h2>
<UL>
<li>PHP</li>
<li>Python</li>
<li>JavaScript</li>
</UL></body>"""

from bs4 import BeautifulSoup
soup = BeautifulSoup(content, 'html.parser')

for parent in soup.li.parents:
    print(parent)
Output is here
<ul>
<li>PHP</li>
<li>Python</li>
<li>JavaScript</li>
</ul>
<body><h2>List of web programming languages</h2>
<ul>
<li>PHP</li>
<li>Python</li>
<li>JavaScript</li>
</ul></body>
<body><h2>List of web programming languages</h2>
<ul>
<li>PHP</li>
<li>Python</li>
<li>JavaScript</li>
</ul></body>
