Quote Guessing Game using Web Scraping in Python

Difficulty Level : Medium
Last Updated : 24 Jan, 2021

Prerequisite: BeautifulSoup Installation

In this article, we will scrape a quote and details of the author from this site http//quotes.toscrape.com using python framework called BeautifulSoup and develop a guessing game using different data structures and algorithm.

The user will be given 4 chances to guess the author of a famous quote, In every chance the user will be provided with a hint which can be the author’s birth date, first name’s first letter, second name’s first letter, etc. On successfully guessing the author, a message is printed and if the user fails to guess the answer even after all the 4 chances then again a message is printed along with the answer.

Approach

Import module
- requests help us grab the page, when the response is received it is stored in the form of a string
- bs4 library is used to create beasutifulSoup object.
- csv library helps reading and writing CSV files using python
- sleep function from time module helps add delay in the execution of the program.
- choice function from random module returns a random element.
Create a list to store values scraped
Scrape the details from this link: http//quotes.toscrape.com
Extract data
Game logic
- Return random items from the dictionary created
- Set number of guesses
- Write message for success and failure
- Keep giving hints until either number of chances reach zero or the user gets it right

Program:

Python3

import requests
from bs4 import BeautifulSoup
from csv import writer
from time import sleep
from random import choice
  
# list to store scarped data

# this part of the url is constant

# this part of the url will keep changing
url = "/page/1"
  
while url:
    
    # concatenating both urls
    # making request
    res = requests.get(f"{base_url}{url}")
    print(f"Now Scraping{base_url}{url}")
    soup = BeautifulSoup(res.text, "html.parser")
  
    # extracting all elements

            "bio-link": quote.find("a")["href"]
        })
    next_btn = soup.find(_class="next")

    guess = input(
        f"Who said this quote? Guesses remaining {remaining_guesses}")
      
    if guess == quote["author"]:
        print("CONGRATULATIONS!!! YOU GOT IT RIGHT")
        break
    remaining_guesses -= 1
      
    if remaining_guesses == 3:
        res = requests.get(f"{base_url}{quote['bio-link']}")
        soup = BeautifulSoup(res.text, "html.parser")
        birth_date = soup.find(class_="author-born-date").get_text()
        birth_place = soup.find(class_="author-born-location").get_text()
        print(
            f"Here's a hint: The author was born on {birth_date}{birth_place}")
      
    elif remaining_guesses == 2:
        print(
            f"Here's a hint: The author's first name starts with: {quote['author'][0]}")
      
    elif remaining_guesses == 1:
        last_initial = quote["author"].split(" ")[1][0]
        print(
            f"Here's a hint: The author's last name starts with: {last_initial}")
      
    else:
        print(
            f"Sorry, you ran out of guesses. The answer was {quote['author']}")
