How to remove quotation and parenthesis around csvwriter output

I have a gps sensor that outputs latitude and longitude. Along with it I am calling the current time in timec(). I want to output these values into a text file that I can upload into excel for extrapolation.
My outputs currently look like

14:48:48,"(36.12306, -97.06177333333332)"

And I need my outputs to look like

14:48:48, 36.12306, -97.06177333333332

I have tried what is below:

import time
import board
import busio

import adafruit_gps
import csv
import serial
import time
from datetime import datetime

def timec():
    now = datetime.now().time()
    current_time = now.strftime("%H:%M:%S")
    return current_time

def GPS():
    uart = serial.Serial("/dev/ttyUSB0", baudrate=9600, timeout=10)
    gps = adafruit_gps.GPS(uart, debug=False)  # Use UART/pyserial
    gps.send_command(b"PMTK314,0,1,0,1,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0")
    gps.send_command(b"PMTK220,1000")
    last_print = time.monotonic()
    while True:
        gps.update()
        current = time.monotonic()
        if current - last_print >= 1.0:
            last_print = current
            if not gps.has_fix:
                print("Waiting for fix...")
                continue

            lat = gps.latitude
            lon = gps.longitude
            return lat,lon

if __name__ == '__main__':
    while True:
        ctime = timec()
        coord = GPS()
        Rows = (ctime,coord)
        with open('Text FILE69', 'a', newline='') as f:
            write = csv.writer(f)
            write.writerow(Rows)
            time.sleep(1)

I know my issue lies with how I call lat and lon. in ‘main’ and the bbottom of GPS()

>Solution :

Spread the result of GPS in to separate variables.

You should just open the file once, not every time through the loop. You can use f.flush() to flush the line to the file immediately.

if __name__ == '__main__':
    with open('Text FILE69', 'a', newline='') as f:
        write = csv.writer(f)
        while True:
            ctime = timec()
            lat, lon = GPS()
            Rows = (ctime, lat, lon)
            write.writerow(Rows)
            f.flush()
            time.sleep(1)
