[Python] Return True/False of EXISTS Postgres query not being recognized by IF statement

def track_exists():
conn = psycopg.connect("dbname=postgres user=postgres password=***)
cur = conn.cursor()
sqltest = "SELECT EXISTS(SELECT 1 FROM CUSTOMERS WHERE CUSTOMERS.PHONE = '608-888-8888')"
cur.execute(sqltest)
result = cur.fetchall()
if result == [(True,)]:
print("working")
dosomething()
elif result == "":
print("not working")


When running this function in VS CODE the output returns exactly, [(True,)] to the screen . My if statement does not recognize this as being true and returns my "not working" statement. No matter what way I've tried different versions of true, IE "True:" , "(True)," "True," etc...

phonestring = phone_str
print (phonestring)
conn = psycopg.connect("dbname=postgres user=postgres password=***)
cur = conn.cursor()
sqltest = "SELECT EXISTS(SELECT 1 FROM CUSTOMERS WHERE CUSTOMERS.PHONE = (%s))"
sqldata = (phonestring)
cur.execute(sqltest,sqldata)
result = cur.fetchone()
if result == [(True,)][0]:
print("Customer Exists")
elif result == [(False,)][0]:
print("New customer")
