What practical experience do you have in applying regular expressions for text processing?

Regular expressions (regex) in Python are often used for searching, replacing, and validating text data.

Practical examples:

• Validating email, phone, and date formats.
• Extracting data from logs or text files.
• Replacing or removing unwanted characters.
• Parsing complex text structures.

Example: extract all emails from text

import re
text = "Contact us: info@example.com or support@test.org"
emails = re.findall(r'[\w.-]+@[\w.-]+\.\w+', text)
print(emails)  # ['info@example.com', 'support@test.org']

Using regular expressions allows for efficient processing and analysis of text data.
