Example: extract email and password from a text file.

gistfile1.txt

import re

# Open the text file
with open("textfile.txt", "r") as file:
    # Read the contents of the file
    data = file.read()

# Use regular expressions to find the email and password in the text
email_regex = r'[\w\.-]+@[\w\.-]+'
password_regex = r'\b[A-Za-z0-9._%+-]+@[A-Za-z0-9.-]+\.[A-Z|a-z]{2,}\b|\b\S{8,}\b'
emails = re.findall(email_regex, data)
passwords = re.findall(password_regex, data)

# Open the output file in write mode
with open("output.txt", "w") as output:
    # Write the emails and passwords to the output file
    for i in range(len(emails)):
        output.write(emails[i] + ":" + passwords[i] + "\n")
