## Exercise 4: Workflow
|
||
|
|
|
||
|
|
#### Goal
|
||
|
|
|
||
|
|
Mimic the *write feature* ⇄ *test feature* workflow.
|
||
|
|
|
||
|
|
#### Tasks
|
||
|
|
|
||
|
|
In the `brew_potions.py` file complete the `make_python_expert_potion` function that makes the *Python expert* potion (instructions below).
|
||
|
|
|
||
|
|
Get Professor Snape to inspect your potion as shown for the example potion. Calling `inspection_by_snape` should never give you an error, so you will have to read what Snape does and says to find out what went wrong.
|
||
|
|
|
||
|
|
This is supposed to be easy and fun, so run the inspection often and make mistakes with the potion.
|
||
|
|
|
||
|
|
Use your git skills to commit the changes you made to a new branch, and create a pull request on Github.
|
||
|
|
|
||
|
|
##### Brewing instructions
|
||
|
|
|
||
|
|
Make a new potion called `python_expert` according to these instructions:
|
||
|
|
|
||
|
|
```
|
||
|
|
1. Set up a pewter cauldron and light a fire underneath it
|
||
|
|
2. Add fish eyes, unicorn hair and tea leaves
|
||
|
|
3. Let simmer for 2 hours
|
||
|
|
4. Have Snape inspect the potion (use target_potion='python_expert').
|
||
|
|
```
|
||
|
|
|
||
|
|
Use the `if __name__ =="__main__"` block in `brew_potions.py` to create the `python_expert` potion and call Snape to inspect the potion by calling `inspection_by_snape` . Make sure you actaully call the function you are editing and change the **target** potion for Snape to `"python_expert"`.
|
||
|
|
|
||
|
|
Note that if you copy from the `example_potion()` function, it is missing a crucial step. You can look at the `Potion()` class in `brewing/potion_class.by` for inspiration.
