Period: 3rd

Teaching Item: Appending Data to Files in Python

Class: Bachelor

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

1. Understand the concept of appending data to existing files.
2. Utilize different methods to append data to text files in Python.
3. Practice appending data to files in various scenarios.

Materials Needed:

• Python interpreter or IDE
• Projector for demonstration

Introduction (5 minutes):

1. Introduce the concept of appending data to files as an extension of reading and writing operations in Python.
2. Explain that appending data allows for adding new information to the end of an existing file without overwriting its contents.
3. Discuss the importance of appending data in scenarios where continuous logging or updating of files is required.

Appending Data to Files (15 minutes):

1. Explain the process of appending data to existing files in Python.
2. Discuss the difference between opening files in write mode ("w") and append mode ("a").
3. Demonstrate how to open a file in append mode using the open() function and the "a" mode parameter.
4. Show examples of using the write() method to append data to the end of a file.
5. Discuss error handling techniques, such as using try-except blocks, when appending data to handle exceptions like FileNotFoundError.

Appending Multiple Lines (10 minutes):

1. Explain how to append multiple lines of data to a file.
2. Demonstrate using a loop to write multiple lines of data to a file in append mode.
3. Discuss best practices for appending data, such as using context managers (with statement) to automatically close files after appending.

Practical Exercises (15 minutes):

1. Provide students with exercises to practice appending data to files in various scenarios.
2. Encourage them to create their own text files and append different types of data, such as strings, numbers, or lists.
3. Circulate around the classroom to provide assistance and guidance as needed.

Conclusion (5 minutes):

1. Summarize the key points covered in the lesson: appending data to files in Python.
2. Reiterate the importance of mastering this skill for managing data effectively in real-world programming scenarios.
3. Encourage students to continue practicing and experimenting with appending data to files to strengthen their understanding.
4. 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 appending data to files in Python.
