Python Regex

Question

I am trying to match a phone number
Where phone number start with 1 or 8 or 9 and total number of digits must be 8.
What am i doing wrong?
import re
n=input()
pattern=r'(1|8|9)[0-9]{7}'
if(re.match(pattern,n)):
print("Valid")
else:
print("Invalid")

Answer 1

It’s likely you need to anchor your match to the end of the string using ‘$’. This avoids matches for inputs more than 8 numbers long. Try

pattern = re.match(r’(1|8|9)[0-9]{7}$’, n))

Answer 2

Jan Markus I see :) it works fine like that.

Answer 3

sid Inputs ‘123456789’ and ‘12345678hello’ are both returning ‘Valid’ which they are not.
