Python f-strings: Embedding expressions inside strings

Python f-strings are the best:

– Put an f before the opening ‘ or “
– Creates a regular string
– Expressions in {} are evaluated/interpolated

x = 5
y = 7
f'{x} + {y} = {x+y}' # 5 + 7 = 12

x = [1,2]
y = [3,4]
f'{x} + {y} = {x+y}' # [1, 2] + [3, 4] = [1, 2, 3, 4]
