My if else command is not working on python

Question

frankly, I'm not a very knowledgeable person in codes, but I wrote a code like this because I could understand the codes a little by fiddling with them, but when it comes to the if else part, the command stops working. There is no problem with the codes inside the else or if. I tried them all, but for some reason it didn't work, please explain with a little clear language.

the code is :

import imaplib
import email
import smtplib

print("lutfen gmail hesabinizdan asagidaki linkteki daha az guvenli uygulama erisimini aciniz")
print("https://myaccount.google.com/lesssecureapps?pli=1&rapt=AEjHL4OQWUSa8LE4ina7cO2HSkmmw2BspYrX6I-LT_hkFhjtpIdTjHNUpc9py5TDlOFjfMRjioLIatn_MSlF3dkutNFeaXmYWg")
print("---------------------------------------------------------------------------------------------------------------------------------------------------------")
host = 'imap.gmail.com'
print("lutfen giris yapiniz")
username = input("gmail hesabinizi yaziniz:")
password = input("gmail hesabinizin sifresini yazin:")

veri: str = input("mail gondermek icin 1 gelen kutunuza bakmak icin 2 yaziniz:")
if veri == 1:
    print("mail gondermeyi sectiniz")
    alici = input("mesaj gondermek istediginiz maili yazin:")

    mesaj = input("gondermek istediginiz mesaji yazin:")

    server = smtplib.SMTP("smtp.gmail.com", '587')
    server.ehlo()
    server.starttls()

    server.login(username, password)
    print("giriş başarılı")

    server.sendmail(username, alici, mesaj)
    print("gönderim tamamlandı")
elif veri == 2:
    def get_inbox():
        mail = imaplib.IMAP4_SSL(host)
        mail.login(username, password)
        mail.select("inbox")
        _, search_data = mail.search(None, 'UNSEEN')
        my_message = []
        for num in search_data[0].split():
            email_data = {}
            _, data = mail.fetch(num, '(RFC822)')
            # print(data[0])
            _, b = data[0]
            email_message = email.message_from_bytes(b)
            for header in ['subject', 'to', 'from', 'date']:
                print("{}: {}".format(header, email_message[header]))
                email_data[header] = email_message[header]
            for part in email_message.walk():
                if part.get_content_type() == "text/plain":
                    body = part.get_payload(decode=True)
                    email_data['body'] = body.decode()
                    print(body)
                    print('----------------------------------------------------------------------')
                elif part.get_content_type() == "text/html":
                    html_body = part.get_payload(decode=True)
                    email_data['html_body'] = html_body.decode()
            my_message.append(email_data)
        return my_message
