Why test case 3 failed?

Question

import re
pattern = r"^(1|8|9)[0-9]{7}"
phone = input()
if re.match(pattern,phone):
print("Valid")
else:
print("Invalid")

Answer 1

try with pattern = r'^(1|8|9)[0-9]{7}#x27; to match full string only ;)

... or shorter: r'^[189]\d{7}#x27;

Answer 2

$ at the end worked... Thank you so much.
