解释一下shell脚本含义，并转换成python脚本 if grep -iw "FT2-MP1" /root/TestPlat/common/test_scene.ini ;then slot_temp=$(cat ${contrl_num}_bus_info.txt | awk -F / '{print $5}' | awk -F "." '{print $2}') else slot_temp=$(cat ${contrl_num}_bus_info.txt | awk -F "/" '{print $7}' | cut -b 9-10)

这段shell脚本的含义是：首先在/root/TestPlat/common/test_scene.ini文件中查找关键字"FT2-MP1"，如果存在，则执行第一条命令，将${contrl_num}_bus_info.txt文件中第5个"/"和"."之间的字符串赋值给变量slot_temp；如果不存在，则执行第二条命令，将${contrl_num}_bus_info.txt文件中第7个"/"后两个字符（即第9到10个字符）的字符串赋值给变量slot_temp。

对应的Python脚本如下：

import os

with open('/root/TestPlat/common/test_scene.ini') as f:
    if 'FT2-MP1' in f.read():
        with open(f'{contrl_num}_bus_info.txt') as f2:
            path_parts = f2.read().split('/')
            if len(path_parts) >= 5:
                slot_temp = path_parts[4].split('.')[1]
            else:
                slot_temp = path_parts[6][8:10]

注意，这里的Python脚本假定了变量`contrl_num`已经被定义。
