Hints

General

• The Python Docs on Control Flow Tools and the Real Python tutorial on conditionals are great places to start.
• The Python Docs on Boolean Operations can be a great refresher on bools, as can the Real Python tutorial on booleans.
• The Python Docs on Comparisons and comparisons examples can be a great refresher for comparisons.

1. Check for criticality

• Comparison operators (comparisons) and boolean operations (concept:python/bools) 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.

     >>> 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 decision "branches".
• Each "branch" can have a separate return, although it might be considered "bad form" by linting tools.
• If the linter complains, consider assigning the output of a branch to a common variable, and then returning that variable.

3. Fail Safe Mechanism

• Comparison operators can be combined and used with conditionals.
• Any number of elif statements can be used as decision "branches".
• Each "branch" can have a separate return, although it might be considered "bad form" by linting tools.
• If the linter complains, consider assigning the output of a branch to a common variable, and then returning that variable.
