I would put this in a helper and raise an CLIAbort exception whenever the split doesn't result in 2 parts in order to prevent this type of error:
```
$ sl lb detail 1234453
Traceback (most recent call last):
  File "/home/kevin/Projects/softlayer-python/SoftLayer/CLI/core.py", line 191, in main
    data = runnable.execute(command_args)
  File "/home/kevin/Projects/softlayer-python/SoftLayer/CLI/modules/loadbal.py", line 226, in execute
    loadbal_id = int(key_value[1])
IndexError: list index out of range
```
