Error

KeyError: '"ip-address"'

When using .format() or f-strings you need to be more careful with your curly braces. Leaving a single { or } gets misinterpreted. If you want to print a single { when using .format() or f-strings you need to instead add {{.

e.g.

name = 'foo'
print(f'{name} }')

gives a syntax error. But:

name = 'foo'
print(f'{name} }}')

gives the desired output: >>> foo }.
