Python - Internet Data Handling
Internet Data Handling in Python
In Python, internet data handling typically involves working with APIs, web scraping, downloading files, and handling HTTP requests and responses. Python provides many modules for Internet data handling, all classified into two categories.
Core Modules
The following are the core modules of the internet data handling:
- urllib: It is useful for working with URLs, fetching data from the web, and handling HTTP requests.
- email: it is useful for parsing, constructing, and sending emails.
- Json: it uses for encoding and decoding JSON data, commonly used in web APIs.
- base64: It encodes and decodes binary data into ASCII text.
Specialized Modules
The following are the specialized modules of the internet data handling:
- requests: It is a more user-friendly HTTP library than urllib.
- BeautifulSoup: It is useful for parsing HTML and XML documents, often used for web scraping.
- lxml: It is a fast and powerful XML and HTML parsing library.
- scrapy: It is a full-fledged framework for web scraping and crawling.
Example
Following is an example of fetching data from a website using the request:
import requests
response = requests.get("https://www.example.com")
if response.status_code == 200:
print(response.text)
else:
print("Error:", response.status_code)Example
Following is an example of Web Scraping with BeautifulSoup and requests:
import requests
from bs4 import BeautifulSoup
url = "https://example.com"
response = requests.get(url)
soup = BeautifulSoup(response.text, 'html.parser')
# Extract all the links on the page
for link in soup.find_all('a'):
print(link.get('href'))Each of these libraries provides advanced tools for working with various aspects of Internet data processing in Python.
