翻译def get_music_name(): """搜索歌曲""" name = entry.get() platfrom = var.get() headers = { 'user-agent': 'Mozilla/5.0 (Windows NT 10.0; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/84.0.4147.105 Safari/537.36', 'x-requested-with': 'XMLHttpRequest' # 判断请求是异步还是同步 }

该函数名为get_music_name,作用是搜索歌曲。在函数中,通过获取entry控件的值,即输入的歌曲名称,以及获取var控件的值,即选择的音乐平台。通过headers参数,模拟请求头部信息,进行搜索。

请将下述shell语言转换为python语言:if [ $HELPs_project_directory ]; then printf "" else # because on sunway platfrom, file name contain symbolic link can not open # thus we should make sure the HELPs directory do not contain symbolic link # first obtain the script directory, this path may contain symbolic link readonly script_directory="$( cd "$( dirname "${BASH_SOURCE[0]}" )" >/dev/null 2>&1 && pwd )" # then remove symbolic link if it exist, the absolute path now obtained readonly HELPs_script_directory=$(readlink -f ${script_directory}) readonly HELPs_project_directory=`dirname ${HELPs_script_directory}` readonly HELPs_build_directory=${HELPs_project_directory}/build readonly HELPs_document_directory=${HELPs_project_directory}/document readonly HELPs_third_party_directory=${HELPs_project_directory}/third_party readonly HELPs_output_directory=${HELPs_project_directory}/output readonly HELPs_HPC_script_directory=${HELPs_project_directory}/HPC_script fi
以下是将上述Shell代码转换为Python代码的示例:
```python
import os
if os.environ.get('HELPs_project_directory'):
print("")
else:
# because on sunway platfrom, file name contain symbolic link can not open
# thus we should make sure the HELPs directory do not contain symbolic link
# first obtain the script directory, this path may contain symbolic link
script_directory = os.path.dirname(os.path.realpath(__file__))
# then remove symbolic link if it exist, the absolute path now obtained
HELPs_script_directory = os.path.realpath(script_directory)
HELPs_project_directory = os.path.dirname(HELPs_script_directory)
HELPs_build_directory = os.path.join(HELPs_project_directory, 'build')
HELPs_document_directory = os.path.join(HELPs_project_directory, 'document')
HELPs_third_party_directory = os.path.join(HELPs_project_directory, 'third_party')
HELPs_output_directory = os.path.join(HELPs_project_directory, 'output')
HELPs_HPC_script_directory = os.path.join(HELPs_project_directory, 'HPC_script')
```
在上述Python代码中,我们使用`os`模块来获取路径和目录,并使用相应的函数替代Shell中的命令。通过这种方式,我们可以在Python中实现与原始Shell代码相同的逻辑。请注意,根据具体情况,你可能需要根据实际需求进行调整和修改。
platform平台驱动结构和platform驱动加载策略,linux内核2.x版本和内核4.x版本以后,platfrom平台驱动有何变化?
在 Linux 内核 2.x 版本中,platform 平台驱动结构是通过一个叫做 platform_device 结构体来表示的,这个结构体包含了设备的名称、ID、资源等信息,并且驱动程序需要通过 platform_driver 结构体来注册这个设备驱动。当设备被检测到时,内核会调用 platform_driver 中的 probe 函数来加载这个驱动程序。
而在 Linux 内核 4.x 版本以后,platform 平台驱动结构发生了一些变化。现在的 platform_device 结构体中包含了更多的设备信息和资源信息,并且驱动程序不再需要显式地注册 platform_driver,而是通过设备树来自动注册 platform_driver。当设备被检测到时,内核会根据设备树中的信息自动匹配合适的驱动程序,并调用其 probe 函数来加载驱动程序。
此外,内核 4.x 版本以后还引入了一种新的驱动加载策略,叫做 device tree overlay。这种加载策略可以让用户在运行时动态地加载和卸载设备树节点以及对应的驱动程序,从而实现更加灵活的设备管理。
