    return vdatetime

    return round(vsize,2)

if __name__ == "__main__":
    fileinfo = os.stat("./binary_tree.docx")
    print("binary_tree.docx的信息:")
    print("文件建立时间：",timestamp_to_string(fileinfo.st_ctime))
    print("文件的大小：",bytetoM(fileinfo.st_size),'M')
    print("文件的修改是时间：",timestamp_to_string(fileinfo.st_mtime))
    print("文件的访问时间：",timestamp_to_string(fileinfo.st_atime))
