Sometimes, you may want to extract both integers and floating-point numbers from a mixed string of text.

import re

# Pattern to match integers and floating-point numbers
pattern = r"[+-]?\d+(\.\d+)?"

# Example text with both integers and floating-point numbers
text = "The values are -20, 15.75, +7, and 3.1415."

matches = re.findall(pattern, text)
print(matches)  # Output: ['-20', '15.75', '+7', '3.1415']

email_pattern = r'^[a-zA-Z0-9._%+-]+@[a-zA-Z0-9.-]+\.[a-zA-Z]{2,}$'
email = 'example@example.com'
if re.match(email_pattern, email):
    print('Valid email')
else:
    print('Invalid email')

text = "Contact me at 123-456-7890 or 987.654.3210"
phone_pattern = r'\d{3}[-.]\d{3}[-.]\d{4}'
phones = re.findall(phone_pattern, text)
print(phones)  # Output: ['123-456-7890', '987.654.3210']
