cclauss d30554bc90 Network F5: Adjust for Python 3 scoping rules (#37554)
This PR makes and adjustment for Python 3 scoping rules which differ from Python 2.  In Python 3, the variable __ex__ goes out of scope at the exit of the __try-except__ block.  This means that when __ex__ is referred to on the lines that follow, it would be an _undefined name_ causing a __NameError__ to be raised instead of the expected __ConnectionError__.
