# Hints
|
||
|
|
|
||
|
|
## General
|
||
|
|
|
||
|
|
- [The Python Tutorial][the python tutorial] can be a great introduction.
|
||
|
|
- [PEP 8][pep8] is the Python code style guide.
|
||
|
|
- [PEP 257][PEP257] details Python docstring conventions.
|
||
|
|
- [Numbers][numbers] in Python can be integers, floats, or complex.
|
||
|
|
|
||
|
|
|
||
|
|
## 1. Define expected bake time in minutes
|
||
|
|
|
||
|
|
- You need to [name][naming] a constant, and [assign][assignment] it an [integer][numbers] value.
|
||
|
|
|
||
|
|
## 2. Calculate remaining bake time in minutes
|
||
|
|
|
||
|
|
- You need to define a [function][defining functions] with a single parameter representing the time elapsed so far.
|
||
|
|
- Use the [mathematical operator for subtraction][numbers] to subtract values.
|
||
|
|
- This function should [return a value][return].
|
||
|
|
|
||
|
|
## 3. Calculate preparation time in minutes
|
||
|
|
|
||
|
|
- You need to define a [function][defining functions] with a single parameter representing the number of layers.
|
||
|
|
- Use the [mathematical operator for multiplication][numbers] 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][return].
|
||
|
|
|
||
|
|
## 4. Calculate total elapsed cooking time (prep + bake) in minutes
|
||
|
|
|
||
|
|
- You need to define a [function][defining functions] with two parameters.
|
||
|
|
- Remember: you can always _call_ a function you've defined previously.
|
||
|
|
- You can use the [mathematical operator for addition][python as a calculator] to sum values.
|
||
|
|
- This function should [return a value][return].
|
||
|
|
|
||
|
|
## 5. Update the recipe with notes
|
||
|
|
|
||
|
|
- Clearly [commenting][comments] and [documenting][docstrings] your code according to [PEP257][pep257] is always recommended.
