python-regexHow to get the href attribute value from a regex in Python?

The href attribute value from a regex can be obtained in Python using the re.findall() function. This function takes a regular expression pattern and a string as arguments and returns a list of all non-overlapping matches in the string.

Example code

import re

html_string = '<a href="https://www.example.com">Example</a>'

href_value = re.findall(r'href="(.*?)"', html_string)

print(href_value)

Output example

['https://www.example.com']

Code explanation

1. import re: This imports the re module which provides regular expression matching operations.
2. html_string = '<a href="https://www.example.com">Example</a>': This is the HTML string from which the href attribute value needs to be extracted.
3. href_value = re.findall(r'href="(.*?)"', html_string): This uses the re.findall() function to extract the href attribute value from the HTML string. The regular expression pattern r'href="(.*?)"' matches the href attribute value and the .*? part captures the value.
4. print(href_value): This prints the href attribute value.
