Email validation

#Email validator
import re


def is_email():
    email=input(\"Enter your email\")
    pattern = \'[\\.\\w]{1,}[@]\\w+[.]\\w+\'
    file = o         


        

Answer 1

You open the variable "file" as a read only then attempt to write to it:

file = open('ValidEmails.txt','r')

Instead, use the 'w' flag.

file = open('ValidEmails.txt','w')
...
file.write(email)
