Python Sendgrid add CC to email

Using the SendGrid's Personalization() or Email() class did not work for me. This is how I got it to work:

from sendgrid import SendGridAPIClient
from sendgrid.helpers.mail import Mail, Cc

# using a list of tuples for emails
# e.g. [('email1@example.com', 'email1@example.com'),('email2@example.com', 'email2@example.com')]
to_emails = []
for r in recipients:
  to_emails.append((r, r))

# note the Cc class
cc_emails = []
for c in cc:
  cc_emails.append(Cc(c, c))

message = Mail(
  from_email=from_email,
  to_emails=to_emails,
  subject='My Subject',
  html_content=f'<div>My HTML Email...</div>'
)

if cc_emails:
  message.add_cc(cc_emails)

try:
  sg = SendGridAPIClient(os.getenv('SENDGRID_API_KEY'))            
  sg.send(message)  
except Exception as e:            
  print(f'{e}')

Hopefully this helps someone.

I resolved it. Santiago's answer got me mostly there, but here is what I needed to do:

sg = sendgrid.SendGridAPIClient(apikey='****')
from_email = Email(sender_address, sender_name)
to_email = Email(to_email)
cc_email = Email(cc_email)
p = Personalization()
p.add_to(to_email)
p.add_cc(cc_email)
subject = subject
content = Content("text/plain", email_message)
mail = Mail(from_email, subject, to_email, content)
mail.add_personalization(p)
response = sg.client.mail.send.post(request_body=mail.get())

If you don't include the p.add_to(to_email) it rejects it because there is no "to email" in the personalization object. Also, if you don't include the "to_email" inside the mail object it rejects it because it is looking for that argument, so you have to be a bit redundant and define it twice.

I've been looking at the code: https://github.com/sendgrid/sendgrid-python/blob/master/examples/mail/mail.py

And it looks like you can do that by adding a personalization to the mail, for example:

cc_email = Email(cc_address)
p = Personalization()
p.add_cc(cc_email)
mail.add_personalization(p)

Based on the answers here you can CC to email if you add another email to 'to_email'.
