Breakfast#
The following code simulates breakfast (you remember something similar from week 4). We’ve added a global variable bread that keeps track of how much bread you have left; you try to toast_bread without any bread, you’ll get an exception.
### Which functions are on the stack when the exception is raised?
- [x] ```make_breakfast```
- [ ] ```fry_eggs```
- [ ] ```buy_bread```
- [x] ```toast_bread```
- [ ] ```wait_for_toaster```
### Which functions have been called at some point in the program when the exception is raised?
- [x] ```make_breakfast```
- [x] ```fry_eggs```
- [ ] ```buy_bread```
- [x] ```toast_bread```
- [ ] ```wait_for_toaster```
### Suppose you were to fix this program by adding an exception handler of the following form:
```python
try:
# ... some existing code ...
except:
buy_bread()
# ... some function call ...
```
Where could you put this code and get the program to work? That is, the program should be unaltered except for the new handler, and the output should be:
```
Sizzle, sizzle
Ding ding!
```
- [x] ```make_breakfast```
- [ ] ```fry_eggs```
- [ ] ```buy_bread```
- [x] ```toast_bread```
- [ ] ```wait_for_toaster```
- [ ] Top-level call to ```make_breakfast```
