排除字典中的文件

def exclude_files(dictionary, file_extension):
    filtered_dict = {}
    for key, value in dictionary.items():
        if not value.endswith(file_extension):
            filtered_dict[key] = value
    return filtered_dict

# 示例字典
file_dict = {
    "file1": "document.txt",
    "file2": "image.jpg",
    "file3": "code.py",
    "file4": "data.csv"
}

# 排除扩展名为".txt"的文件
filtered_dict = exclude_files(file_dict, ".txt")

# 输出结果
for key, value in filtered_dict.items():
    print(key, value)
