Warning is not displayed on the correct line for unknown variables in fstring

Description of your problem

What steps will reproduce the problem? (I did not find an open issue about it but I may be wrong)

1. Create a fstring with an unknown variable (see screenshot)
2. There is a warning message about it but it is displayed on the first line of the script whichever line the issue is

What is the expected output? What do you see instead? The warning message should be in row 10 in the above screenshot

FYI, I believe this is the CPython issue this related to: https://bugs.python.org/issue30465

Thanks @CAM-Gerlach. Indeed, I was considering the python version as the probable root cause. Updating python to 3.6.3 fixes the issue!
