("Debugging") lists three possibilities to consider if a function is not working.
Describe each possibility in your own words.
Define "precondition" and "post condition" as part of your description.
Create your own example of each possibility in Python code. List the code for each example, along with sample output from trying to run it.

How would you write a regex that matches the full name of someone whose last name is Nakamoto? You can assume that the first name that comes before it will always be one word that begins with a capital letter.
The regex must match the following:
• 'Satoshi Nakamoto' • 'Alice Nakamoto' • 'RoboCop Nakamoto'
but not the following:
• 'satoshi Nakamoto' (where the first name is not capitalized) • 'Mr. Nakamoto' (where the preceding word has a nonletter character)
• 'Nakamoto' (which has no first name) • 'Satoshi nakamoto' (where Nakamoto is not capitalized)
The regex must match the following:
• 'Satoshi Nakamoto' • 'Alice Nakamoto' • 'RoboCop Nakamoto'
but not the following:
