Wait for the job to finish

I is it way to wait for the job to finish like in this example : 
```python
job1 = api.analyzers.run_by_name('FileInfo_6_0', {
    'data': '/bin/ls',
    'dataType': 'file'
}, async=True)

# The next instruction should return only Success or Failure, because we reached it after the job finished executing.
print(job1.status)
```

Thank you in advance for your response.
