Not able to exit the loop in python

Question

I am very new to Python and trying to execute below code. The program is to calculate compound interest.

I created basic program and passed values as argument and it worked. Later I created user input program and it worked.

Now when I tried to handle negative or 0 values I am not able to exit program

def CompI(amt, r, t):
    return amt * (pow((1 + r / 100), t)) 

print("Enter Amount")
amt = int(input())
if amt<0 or amt == 0:
    print("Invalid Input")
    exit()

print("Enter rate")
r = int(input())
if r<0 or r == 0:
    print("Invalid Input")
    exit()

print("Enter Time")
t = int(input())
if t<0 or t == 0:
    print("Invalid Input")
    exit()

CI = CompI(amt, r, t)
print("Result is", CI)

---

Result

---

Enter Amount 0 Invalid Input Enter rate

---

when I enter amount as 0 it displays error message and further ask me to enter rate.

Answer 1

maybe try import sys and then use sys.exit() .
