Phone Number Validator

Whats wrong with my code? You are given a number input, and need to check if it is a valid phone number. A valid phone number has exactly 8 digits and starts with 1, 8 or 9. Output "Valid" if the number is valid and "Invalid", if it is not. Sample Input 81239870 Sample Output Valid import re #your code goes here number=input() pattern=r"^{1|8|9}" match= re.match(pattern, number) if match and len(number)==8: print("Valid") else: print("Invalid")

Please re-read the lesson. Groups are formed with [], not with {} Justice It's the regex end-of-module project of Python Core course Dragos Please mention the course name when you refer to a sololearn task.

Are you getting a particular error? Also, it's interesting you're using Regex. I would've just accessed the first character of the string. Ah, nevermind, syntax error like Lisa said.
