[Python] CS50 Python Fuel Gauge

I'm facing a problem with Fuel Gauge CS50's. My code's only passing through half of the requirements. Can someone help me with this one?

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

My result while trying to check:

fuel.py exists
input of 3/4 yields output of 75% - OK
input of 1/3 yields output of 33% - OK
input of 2/3 yields output of 67% - OK
input of 0/100 yields output of E - OK
input of 1/100 yields output of E - OK
input of 100/100 yields output of F - OK
input of 99/100 yields output of F - OK
** input of 100/0 results in reprompt - ERROR
expected program to reject input, but it did not**
input of 10/3 results in reprompt - OK
** input of three/four results in reprompt - ERROR
expected program to reject input, but it did not**
** input of 1.5/4 results in reprompt - ERROR
expected program to reject input, but it did not**
** input of 3/5.5 results in reprompt - ERROR
expected program to reject input, but it did not**
** input of 5-10 results in reprompt - ERROR
expected program to reject input, but it did not**


My code:

def main ():
final_fuel = get_percent()
percent_fuel = round(final_fuel * 100)
if percent_fuel <= 1:
print("E")
elif percent_fuel >= 99:
print("F")
else:
print(f"{percent_fuel}%")


def get_percent():
try:
while True:
fraction = input("Fuel Fraction: ")
x, y = fraction.split('/')
x = int(x)
y = int(y)
fuel = x/y
if fuel <= 1:
return fuel

except (ValueError, ZeroDivisionError):
pass


main ()
