repeating program (python) - loops

Question

Heyho
I want to repeat a program after runnning a task. At the start of the program I ask some questions, than the code jumps into the task. If the task is done the questions sholud ask again..
Each Question reads some infos at the serial port. If i get the infos ten times ich will restart the programm.. but the window closes and i must start the file..
What can i do?
import serial
import struct
import datetime
print("\n")
print("This tool reads the internal Bus ")
print("-----------------------------------------------------------------------")
COM=input("Check your COM Port an fill in with single semicolon (like: 'COM13' ): ")
ser = serial.Serial(
port=COM,
baudrate=19200,
parity=serial.PARITY_NONE,
stopbits=serial.STOPBITS_ONE,
bytesize=serial.EIGHTBITS
)
print("\n")
print("Please choose an option: ")
print("Polling of measured values and the operating status (1)")
print("Reading Parameter memory (2)")
print("Reading Fault memory (3)")
print("EXIT (4)")
print("\n")
i=input("Reading: ")
while(i==1):
count=0
while (count<10):
print(file.name)
print(ser.isOpen())
print ("connected to: "+ ser.portstr)
data = "\xE1\x14\x75\x81"
ser.write(data)
a=(map(hex,map(ord,ser.read(46))))
with open("RS485_Reflex.txt",mode='a+') as file:
file.write(str(datetime.datetime.now()))
file.write(", Values: ,")
file.write(str(a))
file.write("\n")
print(a)
count=count+1
else:
i=0
loop=1
#-----------------------------------------------------------------------
while(i==2):
count=0
while (count<10):
print(file.name)
print(ser.isOpen())
print ("connected to: "+ ser.portstr)
data = "\xE1\x13\x00\x00\x74\x81"
ser.write(data)
a=(map(hex,map(ord,ser.read(11))))
with open("RS485_Reflex.txt",mode='a+') as file:
file.write(str(datetime.datetime.now()))
file.write(", Parameters: , ")
file.write(str(a))
file.write("\n")
print(a)
count=count+1
else:
i=0
#---------------------------------------------------------------------
while(i==3):
count=0
while (count<10):
print(file.name)
print(ser.isOpen())
print ("connected to: "+ ser.portstr)
data = "\xE1\x12\x00\x00\x73\x81"
ser.write(data)
a=(map(hex,map(ord,ser.read(11))))
with open("RS485_Reflex.txt",mode='a+') as file:
file.write(str(datetime.datetime.now()))
file.write(", Fault: , ")
file.write(str(a))
file.write("\n")
print(a)
count=count+1
else:
i=0
#----------------------------------------------------------------------
while(i==4):
file.close()
ser.close()
sys.exit(0)
file.close()
ser.close()

First, you should use If/Elif/Else statements instead of while loops.
while(i==1):
should be
if(i==1)0:
This is a simple program I wrote that you can follow:
# setup a simple run_Task method (prints number of times through the loop already)
def run_task(count):
print "Ran a certain 'task'", count,"times"
# count is a variable that will count the number of times we pass through a loop
count = 0
# loop through 10 times
while(count<10):
# ask questions
q1 = raw_input("What is your name?")
q2 = raw_input("What is your favorite color?")
# run a 'task'
run_task(count)
