Phone Number Validator

Question

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")

Answer 1

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.

Answer 2

Lisa Ooooooooo, I see. Yeah, mentioning the Course/Lesson name would've saved me the questioning LOL

Answer 3

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.

Answer 4

Thanks Lisa, it seems this was the problem.

#your code goes here
number = input()
pattern = r"^[189]+\d{7}quot;
match =re.match(pattern,number)
