You can use a temporary variable, it's not much longer:
print("Iteration {n}: Took {dt) seconds".format(n=n, dt=end-start))
becomes
dt = end - start
print(f"Iteration {n}: Took {dt) seconds")

I'm quite sure that users will write complex code in f-strings.
I vote -1 on the current PEP because of the support of Python code in
f-string, but +1 on a PEP without Python code.
