I am facing the same problem. In the code, it looks like for def checker,
try:
TOR_URL = "https://check.torproject.org/cgi-bin/TorBulkExitList.py?ip=1.1.1.1"
req = requests.get(TOR_URL)
print("\n TOR Exit Node Report: ")
f.write("\n\n --------------------------------- ")
f.write("\n TOR Exit Node Report: ")
f.write("\n --------------------------------- \n")

    f variable is not assign to anything
