如何对我的目录中的每个文件运行这个python函数？

import os
import importlib
import inspect

def process_file(file):
    # 在这里编写对文件的处理逻辑
    print("Processing file:", file)

def run_function_on_files(directory, function_name):
    for file in os.listdir(directory):
        file_path = os.path.join(directory, file)
        if os.path.isfile(file_path) and file.endswith(".py"):
            module_name = os.path.splitext(file)[0]
            module = importlib.import_module(module_name)
            if hasattr(module, function_name):
                function = getattr(module, function_name)
                parameters = inspect.signature(function).parameters
                if len(parameters) == 1 and list(parameters.keys())[0] == 'file':
                    function(file_path)

# 示例用法
directory = "/path/to/your/directory"
function_name = "process_file"
run_function_on_files(directory, function_name)
