my program keeps looping and I don’t know why

the user is required to input package weight and after I input the packages it gives me the correct answer but the answer keeps on repeating.

heres the code:

more = "y"

count = 0

total = 0
x = 0


while(more == "y"):
    lbs = eval(input("Please enter the weight of the package: "))

    if (lbs >= 1 and lbs <= 2):
        op1:(lbs * 1.10)
        x = op1
        count += 1
        total += x
        print("The current package shipping cost is:",op1)

    if (lbs > 2 and lbs <= 6):
        op2 = (lbs * 2.20)
        x = op2
        count += 1
        total += x
        print("The current package shipping cost is:",op2)

    if (lbs > 6 and lbs <= 10):
        op3 =(lbs * 3.70)
        x = op3
        count += 1
        total += x
        print("The current package shipping cost is:",op3)


    if (lbs > 10):
        op4 =(lbs * 3.80)
        x = op4
        count += 1
        total += x
        print("The current package shipping cost is:",op4)

    if (lbs == 0):
        print("your package cannot be delivered")

    more = input ("Do you want to enter another Package? <y/n>: ")
while(more == "n"):
    print("Your total shipping cost is:",total,"for",count,"packages")

   

Answer

This line –

while(more == "n"):
     print("Your total shipping cost is:",total,"for",count,"packages")

You do not need the while loop. Just do –

print("Your total shipping cost is:",total,"for",count,"packages")

Additionally, you do not need eval(), just use int()

lbs = int(input("Please enter the weight of the package: "))

You could use range() function instead of the >= <= … etc. things. For e.g. –

if lbs in range(1,2+1): # Not really useful, still you could use this
    # code

It is not significant, so to keep it simple, you do not need to use the range function
