如何通过re.search在字符串中搜索includes \n

import re

string = "This string includes \n a new line character."
pattern = r"includes \n"
match = re.search(pattern, string)

if match:
    print("Match found!")
else:
    print("No match found.")

if match:
    print("Match found!")
    print("Matched content:", match.group())
    print("Start position:", match.start())
    print("End position:", match.end())
else:
    print("No match found.")
