As for the f-string question... F-strings are "formatting strings." Yes, it is yet another way to format strings in Python. The benefit of it is that is automatically picks up the value of variable named inside it. For instance:

x = "Hello!"
print(f"{x} How are you?")

will print "Hello! How are you?"
