Answer 1

The code coach compares print output and not returned value

So your solution should be printed and not returned

Of course you can make a function that returns the solutions and print its return value

Few pointers to look out for:
Since your solution might print an integer/float value, make sure that you format it properly according to the problem requirements

For example, some problems requires a printing of a value with precision of two decimal places, so if you try to print the float 42.40, it will output as 42.4 and the test will fail.

So that case will require correct formatting

Also look out for printing 0X values such as 05 as int will be printed as 5 and depending on the requirements may also need formatting

Answer 2

You need to call the function:
print(Hovercraft(int(input())))

Also, line 2 should be
"variable_costs = unit_sale * 2000000".

But your code has 2/5 test cases failed.

Answer 3

SoloLearn tests your code with 6 different inputs, and checks whether the output is correct.
