Input and Output in Python

Session Overview

• Focus on input and output in Python.
• Introduction to functions: input and print.

Key Learning Outcomes

• Use input and print functions effectively.
• Format strings using templates and output data in XML or JSON formats.
• Write and read data from files for persistent storage.

Functions and Data Handling

• Importance of input prompting for user interaction.
• Typecasting strings to numeric types for computations.
• Use of print for displaying outputs, with customization of separators and formats.

String Formatting Techniques

• Formatting strings for alignment and length: left, right, center.
• Using template strings for dynamic content generation, utilizing placeholders.

File Operations

• Opening files in Python (reading, writing, appending).
• Importance of closing files to save data.
• Using context manager (with statement) for automatic cleanup after file operations.
• Handling invisible characters (newline) when reading and writing files.

Debugging and Performance

• Use of input as debugging tool to examine execution flow.
• Measuring execution time for algorithms to assess efficiency.

Reminder

• Always ensure to close files after operations to prevent data loss or corruption. Use with statement for automatic management of file resources.
