SO i am making a program for my grampa that calculates his energy bill for him and i am having a problem converting a the bill cost from a str to a int on line 70 it keeps giving me a value error and i cant fix it the number i have been using to test the bill cost is 157.54 if that has anything to do with it so can any of you please help

Right before line 70 print(bill) and print(type(bill)). That may give a clue. Looks like that line should not give an error.

If you want to be able to enter 157.54 you need to convert to a float instead of an int

bill = float(bill)

Don't repeat yourself (DRY)

Think how you can change your code, to remove repeating code. Hint: loops, data structures. You may also break your code into small reusable chunks - functions
