from bs4 import BeautifulSoup
import pandas as pd
from urllib.parse import urlparse, urljoin

# Define the base URL
baseurl = 'https://www.mu.ma/'

# Set to store unique product links
product_links = set()

# Loop through multiple pages of apartment listings
for page_num in range(1, 3):
    # Make a GET request to the page
    r = requests.get(f'https://www.mu.ma/fr/sc/appartements-a-vendre:p:{page_num}')
    soup = BeautifulSoup(r.content, 'html.parser')

   # Extract listings from the page
    listings = soup.find_all(class_='listingBox w100')

    # Loop through each listing and extract product links
    for listing in listings:
        links = listing.find_all('a', href=True)
        for link in links:
            product_link = link['href']

            # Check if the URL is valid
            if not urlparse(product_link).scheme:
                product_link = urljoin(baseurl, product_link)
                product_links.add(product_link)  # Add link to the set

# Initialize list to store scraped data
scraped_data = []

# Loop through each product link and scrape data
for link in product_links:
    try:
        # Make a GET request to the product page
        r = requests.get(link)
        soup = BeautifulSoup(r.content)
        # Extract relevant information from the page
        # (Code snippet continued from previous section...)
    except Exception as e:
        print('Error processing page:', link)
        print(e)
        continue

# Convert scraped data to DataFrame and save to Excel
df = pd.DataFrame(scraped_data)
df.to_excel('scraped_data.xlsx', index=False)

With web scraping as our trusty pickaxe, we delve into the digital mines of the website, extracting nuggets of real estate data to fuel our predictive models and illuminate the path to informed decision-making. Let the data adventure begin! 🏠💻

Data Cleaning

Why Data Cleaning Matters:

Before we can uncover the hidden patterns and insights within our data, we must first ensure its integrity and quality. Data cleaning plays a pivotal role in this process, serving as the foundation upon which our analyses and models are built. By removing inconsistencies, handling missing values, and standardizing formats, we pave the way for accurate and reliable results.

Steps in Data Cleaning:

Removing Duplicates: Duplicate entries can skew our analyses and lead to erroneous conclusions. By identifying and eliminating duplicates, we ensure that each observation contributes meaningfully to our insights.

Handling Missing Values: Missing data is a common challenge in real-world datasets. Whether due to human error or system limitations, missing values must be addressed to maintain the integrity of our analyses. Strategies such as imputation or removal can be employed based on the nature and context of the missing data.

Standardizing Data Types: Inconsistent data types can impede our ability to perform meaningful calculations and comparisons. Standardizing data types ensures uniformity and facilitates seamless data manipulation and analysis.

Python Code Snippets:

# Load the scraped data after some cleaning with VBA Macros

df = pd.read_excel('scraped_data.xlsx')

# Remove duplicate rows

df.drop_duplicates(inplace=True)

# Drop rows with missing prices

df.dropna(subset=['price'], inplace=True)

# Fill missing values in 'city' with corresponding values from 'secteur'

df['city'].fillna(df['secteur'], inplace=True)

# Fill missing values in 'sdb' and 'chambres' with the mean

mean_sdb = df['sdb'].mean()

mean_chambres = df['chambres'].mean()

mean_surface = df['surface'].mean()

df['sdb'].fillna(mean_sdb, inplace=True)

df['chambres'].fillna(mean_chambres, inplace=True)

df['surface'].fillna(mean_surface, inplace=True)

# Fill missing values in 'pieces' with the sum of 'sdb' and 'chambres'

df['pieces'].fillna(df['sdb'] + df['chambres'], inplace=True)

# One-hot encode 'secteur' and 'city' columns

df = pd.get_dummies(df, columns=['secteur', 'city'])

# Display the cleaned DataFrame

print(df.head())

Example:

Let's say our original dataset contains the following entries:
