Why it can't solve test n°4in ?

Question

I'm stuck in this problem, phone number validator in python , this is my code
import re
#your code goes here
pattern = r"^1|8|9 + [0-9]"
num = input()
if re.match(pattern , num) and len(num) == 8:
print ("Valid")
else:
print ("Invalid")
All test except the fourth one how can I pass

Answer 1

# Smile Sam your modified code works well for me:

import re
#your code goes here
pattern = r"^[189]\d{7}quot;
num = input()
if re.match(pattern , num):
print ("Valid")
else:
print ("Invalid")

Answer 2

pattern = r"^[189]\d{7}quot;
if re.match(pattern, num):
...

# no need to check length outside of regexp: last $ mean string end, as ^ mean string start ;)

# here is the minimal change needed:
# pattern = r"(1|8|9)[0-9]+"

Answer 3

Still the same problem does not work for me
