r=requests.get(url)

html_content=r.content

soup=BeautifulSoup(html_content,"html.parser").prettify()

name=soup.find("span",{"class":"B_NuCI"})

Answer 1

Remove the .prettify(), because it will convert your BeautifulSoup object into a string, so you no longer be able to access the info the way you try to do.

The goal of prettify() is to help you visually understand the structure of the documents you work with.

If you just wanna see pretty structure use it only this way print(soup.prettify()) not on BeautifulSoup(...).prettify()

Example

import requests
soup = BeautifulSoup(
            requests.get('https://www.flipkart.com/apple-iphone-14-midnight-128-gb/p/itm9e6293c322a84').text
        )

soup.find('span', class_='B_NuCI').text

Output

APPLE iPhone 14 (Midnight, 128 GB)
