# Hints
|
||
|
|
|
||
|
|
## General
|
||
|
|
|
||
|
|
- The Python Docs on [Control Flow Tools][control flow tools] and the Real Python tutorial on [conditionals][real python conditionals] are great places to start.
|
||
|
|
- The Python Docs on [Boolean Operations][boolean operations] can be a great refresher on `bools`, as can the Real Python tutorial on [booleans][python booleans].
|
||
|
|
- The Python Docs on [Comparisons][comparisons] and [comparisons examples][python comparisons examples] can be a great refresher for comparisons.
|
||
|
|
|

|
|
## 1. Check for criticality
|
||
|
|
|
||
|
|
- Comparison operators and boolean operations can be combined and used with conditionals.
|
||
|
|
- Conditional expressions must evaluate to `True` or `False`.
|
||
|
|
- `else` can be used for a code block that will execute when all conditional tests return `False`.
|
||
|
|
|
||
|
|
```python
|
||
|
|
>>> item = 'blue'
|
||
|
|
>>> item_2 = 'green'
|
||
|
|
|
||
|
|
>>> if len(item) >=3 and len(item_2) < 5:
|
||
|
|
print('Both pass the test!')
|
||
|
|
elif len(item) >=3 or len(item_2) < 5:
|
||
|
|
print('One passes the test!')
|
||
|
|
else:
|
||
|
|
print('None pass the test!')
|
||
|
|
...
|
||
|
|
One passes the test!
|
||
|
|
```
|
||
|
|
|
||
|
|
## 2. Determine the Power output range
|
||
|
|
|
||
|
|
- Comparison operators can be combined and used with conditionals.
|
||
|
|
- Any number of `elif` statements can be used as "branches".
|
||
|
|
- Each "branch" can have a separate `return`
|
||
|
|
|
||
|
|
## 3. Fail Safe Mechanism
|
||
|
|
|
||
|
|
- Comparison operators can be combined and used with conditionals.
|
||
|
|
- Any number of `elif` statements can be used as "branches".
|
||
|
|
- Each "branch" can have a separate `return`
