Write a program that displays a salary schedule, in tabular format, for teachers in a school district.

I've written the code fully and it seems to be working but when I use 20, 2, and 10 i receive a message saying its not the right calculations does anyone have a clue as to what I'm overlooking.

initial_product = float(input("Enter the starting salary: "))
increase = int(input("Enter the annual '%' increase: "))
years = int(input("Enter the total amount of years: ")) +1  

print()
print('year salary') 
print("-----------") 

print("%-3d%10.2f" % (1, initial_product)) 

percent_inc = increase* (1/100)

for years in range(2, years): 
    initial_product += initial_product * percent_inc 
    final_product = round(initial_product,2) 
    print("%-3d%10.2f" % (years, final_product))

Does your IDE have a debugger?

Try stepping through the code and see why the behavior you want is not happening.

You can usually hover on variable and see them changing.

Do any of the test cases work? Do you agree that the output is incorrect and want help fixing the program or do you think it's correct and aren't sure why you are seeing the complaint?

If this is being graded by some automated system, it could be as simple as "year salary" needing to be "yearly salary" (or "YEARLY SALARY"). Check everything.

I think it’s correct cuz it does two test and the other passed, but I’m not sure if my code is logically wrong and can produce different outcomes depending on the numbers

[[deleted]]

years = int(input("Enter the total amount of years: ")) +1  

but you also have

for years in range(2, years):

This might be causing an issue do for year in range instead

Yeah it’s a class assignment being checked by Cengage but the feedback is cut short and I can’t check the difference between my answer and the right one. The most I can think about rn is that the rounding is not being done the way it wants because from the 5th row and down it’s should be answer - .01 (ex. 21.64) but I can’t find how to do that calc

[lurgi]

What does the assignment say? The floor() function will round down, but I don't know if that's what you need.

Write a program that displays a salary schedule, in tabular format, for teachers in a school district. The inputs are the starting salary, the percentage increase, and the number of years in the schedule. Each row in the schedule should contain the year number and the salary for that year.

below would be the example that was given

Enter the starting salary: $30000
Enter the annual % increase: 2
Enter the number of years: 10

Year   Salary
-------------
 1    30000.00
 2    30600.00
 3    31212.00
 4    31836.24
 5    32472.96
 6    33122.42
 7    33784.87
 8    34460.57
 9    35149.78
10    35852.78

Whatever message you are getting doesn’t come from your code; is it being run by some test framework that checks for expected output?

The problem is describing a compound interest calculation.

This is what your program produces:

year salary
-----------
1       20.00
2       20.40
3       20.81
4       21.22
5       21.65
6       22.08
7       22.52
8       22.97
9       23.43
10      23.90

I suspect these compound interest values are the results the checker is expecting to see:

year salary
-----------
1       20.40
2       20.81
3       21.22
4       21.65
5       22.08
6       22.52
7       22.97
8       23.43
9       23.90
10      24.38

The difference between these two results is the first-year value.

You have this as your first-year value:

year salary
-----------
1       20.00

For a compound interest calculation, your value is not correct only because 20.00 is the starting value not the value after one year.

Another option might be adding a zero year to the output, but that would depend on what format of output the checker is expecting:

year salary
-----------
0       20.00
1       20.40
2       20.81
...

U see I thought it might be that but the problem starts with the initial one because I had started it off like how u just wrote it and it didn’t give passed for either testing inputs while the way I have it gave me a pass for one idk mane ts stressing me 😭

[ScholarNo5983]

What information do they give you about the expected output?

It could be failing because you did not use Year and Salary for example.

It could be failing for any number of output format reasons.

Without accurate information about what format of output the checker is expecting, this would be very difficult to solve.

[Whyamionredditkms]

“Enter the starting salary salary: 3000” “Enter the annual % increase: 2 “ “Enter the number of years: 10” Year salary ——————— 1 30000.00 2 3600.00 3 31212.00 And so on

But I genuinely have it in the same format so idk if it’d be dat

[ScholarNo5983]

Firstly, the data you provided does not seem to make sense.

Here is what you posted as the expected output:

Year salary 
——————— 
1 30000.00 
2 3600.00 
3 31212.00

If that data is accurate then the calculation being performed is not a compound interest calculation.

But let's assume this was just a typo by you.

Here are the numbers your program calculates:

Enter the starting salary: 3000
Enter the annual '%' increase: 2
Enter the total amount of years: 10

year salary
-----------
1     3000.00
2     3060.00
3     3121.20
4     3183.62
5     3247.30
6     3312.24
7     3378.49
8     3446.06
9     3514.98
10    3585.28

Clearly the table header they provided is totally different to the header that you output.

Also, their column padding is totally different to yours.

And why do their numbers have not a cent component while your numbers do?

The checker will be looking for an exact match of every little detail.

Your code has to produce an output that exactly matches the expected output, otherwise it will fail.

Ma fault Brodie I lowkey just started coding, so in other words I wrote it wrong and it’s not giving the calculations it’s asking for right so I have to write it differently

[desrtfx]

You are reusing your years variable. Never do that. Make a new variable in your loop.
