me pueden ayudar con un código?

Encontré este código para controlar un motor DC en python en raspberry pi pero me detecta un error en while este es el código :
import RPi.GPIO as IO # calling header file which helps us use GPIO’s of PI
import time # calling time to provide delays in program
IO.setwarnings(False) #do not show any warnings
x=0 #integer for storing the duty cycle value
IO.setmode (IO.BCM) #we are programming the GPIO by BCM pin numbers. (PIN35 as‘GPIO19’)
IO.setup(13,IO.OUT) # initialize GPIO13 as an output.
IO.setup(19,IO.IN) # initialize GPIO19 as an input.
IO.setup(26,IO.IN) # initialize GPIO26 as an input.
p = IO.PWM(13,100) #GPIO13 as PWM output, with 100Hz frequency
p.start(0) #generate PWM signal with 0% duty cycle
while 1: #execute loop forever
p.ChangeDutyCycle(x) #change duty cycle for changing the brightness of LED.
if(IO.input(26) == False): #if button1 is pressed
if(x<50):
x=x+1 #increment x by one if x<50
time.sleep(0.2) #sleep for 200ms
if(IO.input(19) == False): #if button2 is pressed
if(x>0):
x=x-1 #decrement x by one if x>0
time.sleep(0.2) #sleep for 200ms
y esta es la pagina de donde lo saque :

me podrían decir que tengo que cambiar para que funcione o por que no lo hace por favor m_ _m gracias
