Teaching lesson plan 4 Subject: Python programming

Date: 18 Jan 2024

Time: 60 minutes

Period: 3rd

Teaching Item: Exploring Input and Output in Python: Reading and Writing Text Files

Class: Bachelor

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

1. Understand the basics of input and output operations in Python.
2. Read data from text files using various methods.
3. Write data to text files using different techniques.

Materials Needed:

• Python interpreter or IDE
• Projector for demonstration

Introduction (5 minutes):

1. Introduce the concept of input and output (I/O) operations in Python.
2. Explain that input refers to obtaining data from external sources, while output refers to displaying or storing data.
3. Discuss the importance of reading from and writing to text files as common I/O tasks in Python programming.

Reading Text Files (15 minutes):

1. Explain the process of reading data from text files in Python.
2. Discuss different methods for reading text files, such as using open() function with read(), readline(), or readlines() methods.
3. Demonstrate each method with examples, emphasizing their differences and use cases.
4. Discuss error handling techniques, such as using try-except blocks, when reading files to handle exceptions like FileNotFoundError.

Writing Text Files (15 minutes):

1. Explain the process of writing data to text files in Python.
2. Discuss different modes for opening files, such as "w" (write mode), "a" (append mode), and "r+" (read/write mode).
3. Demonstrate how to open a file in write mode and use the write() method to write data to it.
4. Discuss best practices for writing to files, such as using context managers (with statement) to automatically close files after writing.
5. Show examples of writing multiple lines of text to a file and appending data to an existing file.

Practical Exercises (10 minutes):

1. Provide students with exercises to practice reading from and writing to text files.
2. Encourage them to create their own text files and perform various I/O operations on them.
3. Circulate around the classroom to provide assistance and guidance as needed.

Conclusion (5 minutes):

1. Summarize the key points covered in the lesson: input and output in Python, and reading and writing text files.
2. Reiterate the importance of mastering these skills for handling data in real-world programming scenarios.
3. Encourage students to continue practicing and experimenting with reading from and writing to text 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 reading and writing text files in Python.
