Question

In course "Python Core" Code project 91 - Phone Number Validator

Code
---------------------------------------------------------
import re
#your code goes here
pattern = r"\A[189][0-9][0-9][0-9][0-9][0-9][0-9][0-9]\Z"

if re.match(pattern, "57345672"):
print ("Valid")
else:
print ("Invalid")
---------------------------------------------------------
With Input
57345672
returns "Invalid" in IDLE (Python 3.9 64-bit)

But at the site https://www.sololearn.com/learning/eom-project/1073/356
It is written that Your Output "Valid"

Answer 1

I'm not a snobb, thanks

Answer 2

Sorry Thomas, I'll try once more

Answer 3

Dmitry Arkhangelsky That regex makes me cringe (sorry for that). Here is a better alternative for match():

pattern = r"[189]\d{7}quot;

# Hope this helps
# Happy coding!

Answer 4

With my total respect Calvin Thomas, the site rposeeds Your elegant code with the same error

Answer 5

Dmitry Arkhangelsky I just tested my code here. It works just fine.

Answer 6

Hi Thomas! I can't understand what's wrong with the site but sololearn returns 2 errors
-------------------
import re
#your code goes here
pattern = r"[189]\d{7}quot;

if re.match(pattern, "81234567"):
print ("Valid")
else:
print ("Invalid")
