Thank you Simon. I am waiting for the customer give me more details regarding the issue. I will also ask about the Purity version and the Python version that did work as well… Thank you again

looks like this was already reported, with a suggested fix? https://github.com/PureStorage-OpenConnect/nagios-plugins/issues/11

So the f-string is a valid Python string format as described by PEP498. I suspect that using Python 2.7 is the issue, especially as 2.7 is now deprecated and unsupported. I would suggest using a much more modern version of Python, such as 3.8 and seeing it that fails or not.

looks like PEP498 was introduced in python 3.6 - might be worth putting a python version compatibility notice on the repo? definitely sounds like trying python 3.6+ would be the way to go

(given how much legacy python is still out there... )
