Answer 3

Hello guys I can't figure out why Phone Number Validator question of Sololearn can't be solved on the page. This code works on any python editor but refuses on the sololearn page.
This is my code. Anyone who can help me?
import re
#your code goes here
number="57345672"
pattern=r"^[1|8|9]\d{7}quot;
match= re.match(pattern,number)
if(match):
print ("Valid")
else:
print("Invalid")
