'''Time: 60 minutes'''

'''Period: 3rd'''

'''Teaching Item: Exploring the <code>match</code> Function in Python'''

'''Class: Bachelor'''

'''Objective''': 

Students will learn about the <code>match</code> function introduced in Python 3.10, understand its syntax, and explore how it can be used for pattern matching in various scenarios.

Prerequisites: Basic understanding of Python programming language, including variables, data types, functions, and control flow.

'''Materials Needed:'''

* Python interpreter or IDE 
* Projector

'''1. Introduction to Pattern Matching (10 mins)'''

* Define pattern matching:
** Pattern matching is a technique for checking a value against a pattern.
** It allows for concise and readable code when dealing with complex conditional logic.
* Discuss the importance of pattern matching in programming and its advantages over traditional <code>if</code> statements.

'''2. Introduction to the <code>match</code> Function (10 mins)'''

* Introduce the <code>match</code> function:
** The <code>match</code> function is a new feature introduced in Python 3.10 for pattern matching.
** It provides a more concise and readable syntax for pattern matching compared to <code>if</code> statements and <code>elif</code> chains.
* Discuss the syntax of the <code>match</code> function and its basic usage.

'''3. Simple Pattern Matching (15 mins)'''

* Demonstrate simple pattern matching using the <code>match</code> function:
** Show examples of matching literals, variables, and wildcard patterns.
** Discuss the use of <code>case</code> blocks for specifying patterns and corresponding actions.
* Explain how to use the <code>case</code> keyword and patterns to handle different cases.

'''4. Matching Data Structures (15 mins)'''

* Explore pattern matching with data structures such as lists, tuples, and dictionaries:
** Show examples of matching data structures with specific shapes and elements.
** Discuss the use of sequence patterns, mapping patterns, and combination patterns.
* Explain how to destructure data structures and extract values using patterns.

'''5. Guards and Patterns (10 mins)'''

* Introduce guards in pattern matching:
** Guards allow for additional conditions to be checked before a pattern is matched.
** They provide flexibility for handling more complex scenarios.
* Show examples of using guards with patterns to add conditional logic to matches.

'''6. Advanced Topics and Limitations (10 mins)'''

* Discuss advanced topics and limitations of the <code>match</code> function:
** Recursive patterns for matching nested structures.
** Limitations such as lack of support for asynchronous patterns and pattern bindings.
* Highlight the need for understanding when to use <code>match</code> versus traditional <code>if</code> statements based on the complexity of the logic.

'''7. Exercise (10 mins)'''

* Provide a programming exercise where students:
** Write code using the <code>match</code> function to handle different cases based on provided patterns.
** Explore matching various data structures and using guards to add conditional logic.

'''8. Conclusion (5 mins)'''

* Recap the key points covered in the lesson:
** The <code>match</code> function in Python 3.10 provides a concise and readable syntax for pattern matching.
** It allows for matching literals, variables, data structures, and adding guards for conditional logic.
** Understanding pattern matching can lead to more expressive and maintainable code.
* Encourage students to experiment with the <code>match</code> function in their own projects and explore its capabilities further.
