Question

Looking for some help on this exercise, of 5 test examples 4 approved, can't look for the problem cause 5th is locked.
My code goes like this:
purity = float(input())
if purity >= 91.7 and purity <= 99.9:
print("Accepted")

Answer 1

Have corrected it deleting "and purity <= 99.9", 5 of 5 approved.
Seems like 100% of purity is correct for the exercise... 🤷🏻‍♂️
