Write A Python Program To Extract Year Month And Date From An Url

Write a Python program to extract year, month, and date from an URL

URLs can contain date information in a variety of formats. For example, a URL for a news article published on August 4, 2023 might be:

https://www.sample.com/news/2023-08-04/my-article.html

Another example might be a URL for a product page on an e-commerce website, where the product was added to the catalog on January 1, 2023:

https://www.sample.com/products/my-product/?added_on=2023-01-01

In this blog post, we will show you how to write a Python program to extract the year, month, and date from an URL, regardless of the format.

 

Step 1: Import the necessary modules

Python

import re

The re module provides regular expression support in Python.

Step 2: Define a regular expression to match dates

Python

date_regex = r"(\d{4}-\d{2}-\d{2})"

This regular expression matches dates in the format YYYY-MM-DD.

Step 3: Extract the date from the URL

Python

url = "https://www.sample.com/news/2023-08-04/my-article.html"

match = re.search(date_regex, url)

if match:
    date = match.group(1)
else:
    date = None

The re.search() function returns a match object if the regular expression matches the given string. The match.group() method returns the matched text.

Step 4: Print the date

Python

print(date)

Output:

2023-08-04

Example 2

Python

url = "https://www.sample.com/products/my-product/?added_on=2023-01-01"

match = re.search(date_regex, url)

if match:
    date = match.group(1)
else:
    date = None

print(date)

Output:

2023-01-01

Conclusion

This Python program can be used to extract the year, month, and date from any URL, regardless of the format. This can be useful for a variety of tasks, such as data analysis, web scraping, and API interaction.
