Regular Expressions Development Tutorials, Guides & Insights

import re

# Pattern to match only positive numbers (integers and floats)
pattern = r"\+?\d+(\.\d+)?"

# Example text containing positive numbers
text = "Prices increased by +5.75 and 12.99."

matches = re.findall(pattern, text)
print(matches)  # Output: ['+5.75', '12.99']

• By using r"\+?\d+(\.\d+)?", the pattern only matches positive numbers, both with and without a leading +.

• import re: Import the re module to work with regular expressions.

pattern = re.compile(r'\d+')
