Is it possible to use a variable inside of a Python string formatting specifier?
I have tried:
display_width = 50
print('n{:^display_width}'.format('some text here'))
but get a ValueError: Invalid format specifier. I have also tried display_width = str(50)
however, just entering print('n{:^50}'.format('some text here')) works just fine.

Yes, but you have to pass them in as arguments to format, and then refer to them wrapped in {} like you would the argument name itself:
print('n{:^{display_width}}'.format('some text here', display_width=display_width))
Or shorter but a little less explicit:
print('n{:^{}}'.format('some text here', display_width))
