Newbie with Pi3

Of course, not able to test, but something like this

import RPi.GPIO as GPIO
import time
from twilio.rest import Client


def send_sms(client, sms_text="Hello from Python!"):
    client.messages.create(to="+19732644152", 
                           from_="+12023351278", 
                           body=sms_text)


twilio_client = Client("ACxxxxxxxxxxxxxx", "zzzzzzzzzzzzz")
                           
GPIO.setmode(GPIO.BOARD)
GPIO.setwarnings(False)
GPIO.setup(7,GPIO.IN)   #LDR (Light Dependent Resistor)
#GPIO.setup(11,GPIO.IN)  #Top Switch
#GPIO.setup(12,GPIO.IN)  # Bottom Switch

GPIO.setup(11, GPIO.IN, pull_up_down=GPIO.PUD_DOWN) #top switch
GPIO.setup(12, GPIO.IN, pull_up_down=GPIO.PUD_DOWN) # bottom switch

GPIO.setup(15,GPIO.OUT) # Door Open
GPIO.setup(13,GPIO.OUT) # Door Close

delay1 = 1  # time between checks when door moving for switch operation may need to be shorter 
delay2 = 5  # time between checks of LDR

while True:
    while GPIO.input(7) == False:
        if GPIO.input(11) == False:
            print ("Day")
            print ("Open door")
            GPIO.output(15,True)
            print ("drive motor")
            print ("Current time %s"  % now )
        elif GPIO.input(11) == True:
            GPIO.output(15,False)
            print ("STOP door open")
            send_sms(client=twilio_client, sms_text='Door open')
        time.sleep(delay1)
    time.sleep(delay2)

    while GPIO.input(7) == True:
        if GPIO.input(12) == False:
            print ("Night")
            print ("Close door")
            GPIO.output(13,True) 
            print ("drive motor")
        elif GPIO.input(12) == True:
            GPIO.output(13,False)
            print ("STOP door closed")
            send_sms(client=twilio_client, sms_text='Door closed')
        time.sleep(delay1)       
    time.sleep(delay2)

I changed the indentation to 4 spaces, as per PEP8. 8 spaces per level is way too much.
Didn't change the rest of the code, but probably it could be written better. At least, based on https://sourceforge.net/p/raspberry-gpio...ki/Inputs/ it's better to use edge detection than pooling
