在python中按日期时间对文件进行排序

import os

def sort_files_by_datetime(directory):
    file_dict = {}
    for filename in os.listdir(directory):
        filepath = os.path.join(directory, filename)
        if os.path.isfile(filepath):
            file_dict[filename] = os.path.getmtime(filepath)
    
    sorted_files = sorted(file_dict.items(), key=lambda x: x[1])
    
    sorted_filenames = [filename for filename, _ in sorted_files]
    
    return sorted_filenames

# 示例用法
sorted_filenames = sort_files_by_datetime('/path/to/directory')
for filename in sorted_filenames:
    print(filename)
