I hope this will provide a better idea of what I need. I'm not even sure it is possible though.

I'm running this script to test the Serial connection between an Arduino and Python before I try to send and receive information between the two.
If the Arduino is unplugged/re-plugged during while ser.read(), it will never restart from where it left off due to never receiving anything but a '1' from the Arduino>Serial.
What is a better way to write this that ensures the Serial connection can restart the script from the beginning after being unplugged?
from pprint import pprint
import time
import serial
while True:
#the connection to the arduino
try:
ser = serial.Serial('COM13',9600)
except IOError:
connected = False
pprint('Arduino not connected to COM13')
time.sleep(3)
continue
serin = ser.read()
connected = True
pprint('connected to arduino')
ser.write('1')
while ser.read() == '1':
pass
pprint ('Arduino has finished flash')
ser.close()
pprint('connection closed')
time.sleep(5)
