Counting the number of p-tags (<p>) in a website from a user's choice of link input in Python 3

Write a program that asks the user for a URL. It should then retrieve the contents of the page at that URL and print how many <p> tags are on that page. Your program should just print an integer.

Here's my code:

import urllib.request

link = input('Enter URL: ')
response = urllib.request.urlopen(link)
html = response.read()
counter = 0
for '<p>' in html:
    counter += 1
    print(counter)

However, I got this error:

Traceback (most recent call last):

  File "python", line 16

SyntaxError: can't assign to literal

What would be the better method to execute this code? Should I use the find method instead?

This code works good:

from lxml import html
import requests
page = requests.get(input('Enter URL: '))
root = html.fromstring(page.content)
print(len(root.xpath('//p')))

Try to use BeautifulSoup

from bs4 import BeautifulSoup
import requests

link = input('Enter URL: ')
response = requests.get(link)
html = response.text

soup = BeautifulSoup(html, 'lxml')
tags = soup.findAll('p')

print(len(tags))

First of all response.read() returns bytes; hence you need to cast it to string:

html = str(response.read())

then, no need for for loop, you can just use count = html.counter('<p>')

Hope it help.s
