如何在python中将正则表达式匹配的一部分作为变量？

import re

text = "Hello, my name is John Doe and I am 30 years old."
pattern = r"my name is (.*) and I am (\d+)"

match = re.search(pattern, text)

if match:
    name = match.group(1)
    age = match.group(2)
    print(f"Name: {name}, Age: {age}")
else:
    print("No match found.")

Name: John Doe, Age: 30

import re

text = "Hello, my name is John Doe and I am 30 years old."
pattern = r"my name is (.*) and I am (\d+)"

match = re.search(pattern, text)

if match:
    name = match.group(1)
    age = match.group(2)
    print(f"Name: {name}, Age: {age}")
else:
    print("No match found.")

Name: John Doe, Age: 30
