TypeError: 'list' object is not callable, though I am just passing a list to a function as an argument (Python)

Question

我目前正在编写一个使用强连接类并根据命令名称运行特定功能的框架。

在编写一个仅将一个列表和一个函数传递到另一个列表的函数时，我运行遇到了这个问题：

File "main.py", line 6, in <module>
    framework.module("modules.banner", console)
  File "C:\Users\Default\Desktop\Framework\framework\framework.py", line 53, in module
    new = importlib.import_module(module)
  File "C:\Program Files (x86)\Python38-32\lib\importlib\__init__.py", line 127, in import_module
    return _bootstrap._gcd_import(name[level:], package, level)
  File "<frozen importlib._bootstrap>", line 1014, in _gcd_import
  File "<frozen importlib._bootstrap>", line 991, in _find_and_load
  File "<frozen importlib._bootstrap>", line 975, in _find_and_load_unlocked
  File "<frozen importlib._bootstrap>", line 671, in _load_unlocked
  File "<frozen importlib._bootstrap_external>", line 783, in exec_module
  File "<frozen importlib._bootstrap>", line 219, in _call_with_frames_removed
  File "C:\Users\Default\Desktop\Framework\modules\banner.py", line 5, in <module>
    class Banner:
  File "C:\Users\Default\Desktop\Framework\modules\banner.py", line 41, in Banner
    event.commands(exit_console, commands)
TypeError: 'list' object is not callable

调用该函数的脚本：

...
class Banner:
...
    @event.event
    def on_ready():
        self.banner()
    
    def exit_console():
        print("3[1;32;0m")
        quit()

    command_names = ["exit", "quit", "e", "q"]
    event.commands(exit_console, command_names)
...

event.commands函数：

...
class event:
    def __init__(self):
        self.events = []
        self.commands = []
        self.parsers = []

    def event(self, function):
        self.events.append(function)
    def command(self, function):
        self.commands.append([function.__name__, function])
    def commands(self, function, lt):
        for name in lt:
            self.commands.append([name, function])
...

command和commands的区别是command取一个命令名，commands取多个。

event.command 示例：

...
@event.command
    def ping(args):
        print(args)
...

在此先感谢，我一直在寻找很多论坛，但找不到任何东西。

在您的 event class 中，您将 commands 定义为一个列表和一个函数。这就是导致错误的原因。

class event:
    def __init__(self):
        self.events = []
        self.commands = [] #list here
        self.parsers = []

    def event(self, function):
        self.events.append(function)
    def command(self, function):
        self.commands.append([function.__name__, function])
    def commands(self, function, lt): #function here
        for name in lt:
            self.commands.append([name, function])
