Overwrite previous live data.

[Makada]

Hi,

I am trying to output the current code, which is working ok.
But i want the output to overwrite previous data instead of append.

import requests
import csv
import time
import schedule
from time import sleep
import sys
import csv
import io
starttime=time.time()

def task():
    with io.open('C:\\Campbellsci\\LoggerNet\\CR1000_Public.dat') as f:
        reader = csv.reader(f, delimiter=',')
        
        for field in reader:
            a = (field[6])
            print(a)
            
while True:
 try:
     task()
     time.sleep(0.25 - time.time() % 0.25)
     refresh()
 except:
    pass
    time.sleep(0)
else:
 time.sleep(0)
 refresh()

Here is the output:

Python 3.8.3 (tags/v3.8.3:6f8c832, May 13 2020, 22:37:02) [MSC v.1924 64 bit (AMD64)] on win32
