Hello. I just want someone to check this code. is

it correct use of exception handling? also did i do right putting if condition to check if x is greater than y or is there any way i can check that using try except?

https://cs50.harvard.edu/python/2022/psets/3/fuel/

while True:
try:
x, y = map(int, input('Fraction: ').split('/'))
perc = int(round((x/y)*100))
if x>y:
continue
except(ValueError, NameError, ZeroDivisionError):
pass
else:
if perc<=1:
print('E')
elif perc>=99:
print('F')
else:
print(f'{perc}%')
break

Oh. Yes i forgot. I used it in previous exercise. I used it just in case the input doesn't get stored in variable, but here I'm asking for input again so it's useless. Thanks

... yes, the assert and raise keywords raise exceptions, which you can handle

you can use the assert or raise keywords for the comparison, but i think it's fine
