Trying to make an install script for Deskpi Pro case

I'm having a hard time with this code:

import serial
import time
import subprocess


ser=serial.Serial("/dev/ttyUSB0", 9600, timeout=30)


try:
 while True:
 if ser.isOpen():
 cpu_temp=subprocess.getoutput("/opt/vc/bin/vcgencmd measure_temp" | "sed -e "s/temp=//" -e "s/\..*'/ /")
 cpu_temp=int(cpu_temp.split(.)[0])


 if cpu_temp < 40:

 ser.write(b'pwm_000')

 elif cpu_temp > 40 and cpu_temp < 50:

 ser.write(b'pwm_025')

 elif cpu_temp > 50 and cpu_temp < 65:

 ser.write(b'pwm_050')

 elif cpu_temp > 65 and cpu_temp < 75:

 ser.write(b'pwm_075')

 elif cpu_temp > 75:

 ser.write(b'pwm_100')



except KeyboardInterrupt:

 ser.write(b'pwm_000')

 ser.close()

I'm pretty sure it's a formatting issue, but I can't seem to figure this part out:

try:
 while True:
 if ser.isOpen():
 cpu_temp=subprocess.getoutput("/opt/vc/bin/vcgencmd measure_temp" | "sed -e "s/temp=//" -e "s/\..*'/ /")
 cpu_temp=int(cpu_temp.split(.)[0])

I keep getting errors, regardless of my changes. I get "unsupported operand type(s) for "|:" 'str' and 'str' " "syntax errors"

Honestly I can barely read this. Can someone please point me in the right direction?
Anything will help.

Thanks in advance!

cpu_temp=subprocess.getoutput("/opt/vc/bin/vcgencmd.measure_temp") | "grep" "sed -e s/temp=// -e s/\..*'/ /"
cpu_temp=float(int(cpu_temp.split('.')[0]) 

Looks like the error I was getting was because I was trying to take a LITERAL(real number) into an Integer.

You can't do that, so you have to turn it into a FLOAT.

Adding "float(" in-front of the other code I had(int(cpu_tempt.split....) "fixed" it.

But now I'm getting an error here:

if cpu_temp < 40:

                ^
SyntaxError: invalid syntax

Ahh crap i put this in the wrong thread.

and the code I thought fixed this. didn't.
