TypeError: 'NoneType' object is not iterable

TypeError: 'NoneType' object is not subscriptable

This error occurs when you try to use the integer type value as an array. In simple terms, this error occurs when your program has a variable that is treated as an array by your function, but actually, that variable is an integer.

TypeError: 'NoneType' object is not iterable

def write_file(data, filename): # creates file and writes list to it
  with open(filename, 'wb') as outfile:
    writer = csv.writer(outfile)
    for row in data: # ABOVE ERROR IS THROWN HERE
      writer.writerow(row)
