How to update postgresql table via Python

conn = psycopg2.connect(database = database,
user = user_name,
password = password,
host = host,
port = port)
print("Database Connection Successful")
cursor = conn.cursor()
query = "select id from contact where owner_company_id =7295373"
cursor.execute(query)
contact = list(cursor.fetchall())
print(contact)
for info in contact:
id = info[0]
print(id)
ivurl = f'{api}/company/{id}/contacts?'
payload: Dict[str, Union[bool, int]] = {'id': True}
response = get_iv_response(url=ivurl, payload=payload)
email_contact_totalresult: int = response.get('totalResults')
email = int(email_contact_totalresult)
payload: Dict[str, Union[bool, int]] = {'name': True}
response = get_iv_response(url=ivurl, payload=payload)
phone_contact_totalresult: int = response.get('totalResults')
phone = int(phone_contact_totalresult)
print ("here")
if email > 0 or phone > 0:
print (f"{id} has contacts")
else :
print (f"{id} doesnot has contacts")
update_query = (f"UPDATE table_name set has_contact = true where id = {id}")
print(update_query)
cursor.execute(update_query)
