I can't pass Test Case 3 in Code Project – Phone Number Validator

Hello everyone, I need a help. In the block Regular Expressions I can not pass internal Test Case 3. Task: Phone Number Validator 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 My code: import re #this is my code tel_number = input() pattern = r"[189]\d{7}" if re.match(pattern, tel_number): print('Valid') else: print('Invalid')

Lyapunov Alexander , you have been very close, only '
#x27; was missing at the end of the pattern: pattern = r"[189]\d{7}" # your pattern pattern = r"[189]\d{7}
quot; # correct pattern

Yes, I used pattern = r'^[189]\d{7}
#x27; and it correctly.
