My code will not write to an unprotected txt file

Question

I have a piece of code for a live sub count, which works perfectly, but I wanted to then add those results to a file called 'history.txt', however when I run the code, even if I leave it for quite a while, for the loops to have looped plenty of times, my txt file stays empty.

(code is below) (i KNOW its sloppy don't judge me)

import requests
import time
import os
from time import gmtime, strftime

open("history.txt", "w").close()

histTx = open("history.txt", "a")

def simp():
  global histTx
  u = input("Input the URL of the channel page:\n")
  p = True
  while p:
    try:
      u.index("http")
    except ValueError:
      u = "http://" + u
    response = requests.get(u)
    r = str(response.content).lower()

    locator = r.index("subscribers")
    goBack = locator
    while not r[goBack] == "\"":
      goBack -= 1
    goBack += 1
    os.system('clear')
    print("\033[1;36;48m", r[goBack : locator].upper())
    print("---------\n")
    time.sleep(2.5)
    os.system('clear')
    histTx.write(str(r[goBack : locator].upper()))

def adv():
  global histTx
  u = input("Input the URL of the channel page (input -1 for simple mode):\n")
  if u == "-1":
    simp()
  else:
    p = True
    while p:
      try:
        u.index("http")
      except ValueError:
        u = "http://" + u
      response = requests.get(u)
      r = str(response.content).lower()

      locator = r.index("subscribers")

      goBack = locator
      while not r[goBack] == "\"":
        goBack -= 1
      goBack += 1
      os.system('clear')
      print("That channel has \033[1;36;48m" + r[goBack : locator].upper() + "\033[0mSubscribers.\n")
      print("---------\n")
      time.sleep(2.5)
      os.system('clear')
      histTx.write(str(r[goBack : locator].upper()))

adv()

(Before you ask, no errors, and history.txt does exist.)

Answer 1

The problem is that it should be def simp(histTx) and def adv(histTx) , and it should have simp(histTx) and adv(histTx) when running it.
