directed replies to the tutor list. - Cameron

Thanks a lot for your quick responses, Could you please let me know
when the device is not enabled I get the error " I get the below error
saying "IndexError: list index out of range""
Code snippet:
[...]
res = self._helper.execute_cmd_output_string(cmd)
print("The value of res!!!!", res)
res = self._helper.execute_cmd_output_string(cmd).split("\n", 2)
print("the value!!!!!!!!!!!!", res)
print("the value!!!!!!!!!!!!", res[1])
if __name__ == "__main__":
m = Bt()
print(m.bluetooth_scan())
1. Output when device is enabled:
The value of res!!!! Scanning ...
64:A2:F9:06:63:79 OnePlus 6
the value!!!!!!!!!!!! ['Scanning ...', '\t64:A2:F9:06:63:79\tOnePlus 6']
the value!!!!!!!!!!!! 64:A2:F9:06:63:79 OnePlus 6
None
The "None" is because your bluetooth_scan method has no return value (I
think), which in Python it means it returns None.
2. Output when device is not enabled
When the device is not connected, I get the below error saying
"IndexError: list index out of range"
The value of res!!!! Scanning ...
Traceback (most recent call last):
the value!!!!!!!!!!!! ['Scanning ...']
File "/home/srinivasan/Downloads/bt_tests/qa/test_library/Bt.py",

print(m.bluetooth_scan())
File "/home/srinivasan/Downloads/bt_tests/qa/test_library/Bt.py",
line 74, in bluetooth_scan
print("the value!!!!!!!!!!!!", res[1])
IndexError: list index out of range
Well, you've printed your list:
['Scanning ...']
It is a single element list. So it has an element at index 0. There is
no element 1. Therefor Python raises an IndexError if you try to access
that element.
