Hints

General

• The Python Tutorial can be a great introduction.
• [PEP 8][pep8] is the Python code style guide.
• PEP 257 details Python docstring conventions.
• Numbers in Python can be integers, floats, or complex.

1. Define expected bake time in minutes

• You need to name a constant, and assign it an integer value.

2. Calculate remaining bake time in minutes

• You need to define a function with a single parameter representing the time elapsed so far.
• Use the mathematical operator for subtraction to subtract values.
• This function should return a value.

3. Calculate preparation time in minutes

• You need to define a function with a single parameter representing the number of layers.
• Use the mathematical operator for multiplication to multiply values.
• You could define an extra constant for the time in minutes per layer rather than using a "magic number" in your code.
• This function should return a value.

4. Calculate total elapsed cooking time (prep + bake) in minutes

• You need to define a function with two parameters.
• Remember: you can always call a function you've defined previously.
• You can use the mathematical operator for addition to sum values.
• This function should return a value.

5. Update the recipe with notes

• Clearly commenting and documenting your code according to PEP257 is always recommended.
