HELP!!

Question

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

def valid(s):
pattern = re.compile("^[189]\d\d\d\d\d\d\d")
return pattern.match(s)

s = input("")
if (valid(s)):
print("Valid")
else:
print("Invalid")

When I run this in sololearn terminal while submitting my project it works completely fine but still got 1 error and I'm not able to find that 1 little error.
Idk whats wrong with this code pls let me know whats wrong and do correct me!

Thank you in advance

Answer 1

I think you forgot the $ sign which indicates the end, it must be used because you have "^" which indicates start.

And just additional info, instead of typing " \d " 7 times you can just do " \d{7} " 7 inside the bracket means the number of repetition.

I hope this helps. If you need more explanation, feel free to ask. Thanks and Happy Coding!
