Python | Calculate discount based on the sale amount using Nested if else

Program:

# input sale amount 
amt = int(input("Enter Sale Amount: "))

# conditions to check amount and get discount
if(amt>0):
    if amt<=5000:
       disc = amt*0.05
    else:
        if amt<=15000:
            disc=amt*0.12
        else:
            if amt<=25000:
                disc=0.2 * amt
            else:
                disc=0.3 * amt
    
    # printing discount and net payable amount 
    print("Discount : ",disc)
    print("Net Pay  : ",amt-disc)
else:
    print("Invalid Amount")

Output

Enter Sale Amount: 22000
Discount :  4400.0
Net Pay  :  17600.0
