Here is the code. 2 functions.
def get_domains(self): #returns [email protected], [email protected] etc in json.
if self.domain_names == None:
r = requests.get(GET_DOMAINS_URL)
if r.status_code != 200:
raise ValueError("Can't get domains")
self.domain_names = [item["name"] for item in r.json()]
return self.domain_names
def is_valid_email(self, email):
return email[email.find("@") 1:] in self.get_domains()
So what does part " 1:" in function is_valid_email ? How it works?
CodePudding user response:
This is a string slicing:
email[email.find("@") 1:]
It means - take all the characters from email
string from the first index after the @
char till the end of string.
Or in simple words - extract the domain from an email address :)
