如果在第一组数据中找不到第二个数据组，该如何循环？

Question

如果在第一组数据中找不到任何内容，如何遍历第二组数据？

正在循环的数据

flow start IOUFlow iouValue: 99, otherParty: PartyB

代码段

In [113]: bpimage_cmd_split
Out[113]:
['Client:            hostname',
 'Backup ID:         hostname_1555238197',
 'Policy:            Policy1',
 'Proxy Client:      (none specified)',
 'Job ID:            4630451',
 'Data_Classification_ID: (none specified)',
 'Storage Lifecycle Policy:    SLP-DATA-Infinite',
 'Origin Master GUID:    (none specified)',
 ' ID:               @aaaaC',
 ' ID:               @aaaaE',
 ' ID:               L02551',]

In [151]: type(bpimage_cmd_split)
Out[151]: list

代码按预期工作。

但是，通过更多的质量检查测试，来自last_backup_image，bpimage_cmd_split的数据是否有“ ID：”，就像所有@aaaa一样，因为备份作业仍在运行？如果是这种情况，那么我希望它遍历“ second_backup_image”并获取不包含@aaa的ID？

Answer 1

if "ID" not in backup_client_info: 
    bpimage_cmd = ssh_connect.run(rf"sudo /usr/openv/netbackup/bin/admincmd/bpimagelist -L -backupid {second_backup_image} -media | egrep -e 'Policy:' -e 'ID:' -e 'Client:'")
