'''Time: 60 minutes'''

'''Period: 3rd'''

'''Teaching Item: Writing Binary Files Manually in Python'''

'''Class: Bachelor'''

'''Objective:''' By the end of this lesson, students will be able to:

# Understand the concept of binary files and their importance in handling non-textual data.
# Learn how to write binary data to files in Python manually.
# Practice writing various types of binary data to files.
'''Materials Needed:'''
* Python interpreter or IDE
* Projector for demonstration
'''Introduction (5 minutes):'''
# Introduce the concept of binary files and explain their significance in handling non-textual data, such as images, audio, video, and binary-encoded data.
# Discuss the difference between text and binary files, emphasizing that binary files store data in its raw binary format, while text files store data as human-readable characters.
# Explain that writing binary data to files manually gives programmers more control over the format and structure of the data.

'''Writing Binary Data to Files (20 minutes):'''

# Explain the process of writing binary data to files in Python.
# Discuss the <code>open()</code> function with the <code>"wb"</code> mode parameter for opening files in binary write mode.
# Demonstrate how to open a file in binary write mode and use the <code>write()</code> method to write binary data to it.
# Discuss the differences between writing binary data and writing text data to files, such as the need to encode data as bytes before writing.
# Show examples of writing different types of binary data to files, such as integers, floating-point numbers, and byte arrays.
# Discuss error handling techniques, such as using <code>try-except</code> blocks, when writing binary data to handle exceptions like <code>FileNotFoundError</code>.

'''Writing Binary Data from Objects (10 minutes):'''

# Discuss how to write binary data from objects to files.
# Demonstrate how to serialize objects using libraries like <code>pickle</code> or <code>struct</code> before writing them to binary files.
# Show examples of serializing and writing objects to binary files, such as dictionaries, lists, or custom classes.

'''Practical Exercises (10 minutes):'''

# Provide students with exercises to practice writing various types of binary data to files.
# Encourage them to experiment with writing different types of data and exploring the resulting binary files.
# Circulate around the classroom to provide assistance and guidance as needed.

'''Conclusion (5 minutes):'''

# Summarize the key points covered in the lesson: writing binary files manually in Python.
# Reiterate the importance of understanding binary files for handling non-textual data effectively in programming.
# Encourage students to continue practicing and experimenting with writing binary data to files to strengthen their understanding.
# Invite questions from students and address any remaining doubts or confusion.

'''Assessment:'''

* Informal assessment through observation of students' participation in discussions and activities.
* Review students' completed exercises or tasks to assess their understanding of writing binary files manually in Python.
