import re

# Pattern to match signed and unsigned integers/floats
pattern = r"[+-]?\d+(\.\d+)?"

# Complex string with embedded numbers
text = "In 2021, the growth was +6.5%, compared to -3.14% in 2020."

matches = re.findall(pattern, text)
print(matches)  # Output: ['2021', '+6.5', '-3.14', '2020']

• This pattern efficiently extracts all numeric values from a string, whether they are positive or negative, whole numbers or floating points.
