  • Indexing, slicing, immutability, string concatenation, escaping, multi-line strings.

Exam Block #3: Functions and Generators (15%)

Functions are the building blocks of reusable code in Python. This section will help you understand how to define, use, and manage functions, including generators for memory-efficient operations.

Objectives Covered:

• PCEP 3.1 Decompose the code using functions

  • Defining functions, recursion, returning values, the None keyword, handling multiple return values.

• PCEP 3.2 Organize interaction between the function and its environment

  • Parameters vs. arguments, default parameter values, name scopes, shadowing, the global keyword.

• PCEP 3.3 Understand Python's Exception Hierarchy

  • BaseException, Exception, SystemExit, KeyboardInterrupt, abstractive exceptions, arithmetic and value errors, assertions.

• PCEP 3.4 Implement Python Exception Handling

  • Try-except blocks, handling multiple exception types, exception propagation, delegating exception handling responsibilities.

Exam Block #4: Modules, File I/O and Debugging (15%)

Expand your Python knowledge by learning to use modules, handle file input/output operations, and debug your code effectively. These skills are essential for building robust applications.

Objectives Covered:

• PCEP 4.1 Utilize Python Modules

  • Importing standard and third-party modules, exploring the module namespace.

• PCEP 4.2 Perform file I/O operations

  • Reading from and writing to files, handling different file modes, exception handling for file operations.

  • Using Python's debugger pdb, writing tests with the unittest framework.

Exam Block #5: Working with Datetime and Time (10%)

Time-related operations are crucial for many applications. This section covers everything you need to know about handling dates, times, and time zones in Python.

Objectives Covered:

• PCEP 5.1 Work with the datetime module

  • Date and time representation, formatting, parsing, and manipulating time data.

• PCEP 5.2 Handle time zones effectively

  • Working with time zone differences, converting between them.

Exam Block #6: Classes and Object-Oriented Programming (10%)

Understanding object-oriented programming (OOP) principles is vital for writing maintainable and scalable Python code. This section delves into creating classes, understanding inheritance, and implementing polymorphism.

Objectives Covered:

• PCEP 6.1 Design classes and objects

  • Class creation, attributes and methods, __init__, class variables vs. instance variables.

• PCEP 6.2 Implement inheritance

  • Extending classes, super() for parent calls, method overriding.

• PCEP 6.3 Implement polymorphism

  • Method overloading using function arguments, operator overloading in Python.

Additional Tips:

• Practice: Work through the official Python tutorial and documentation.
• Code Examples: Review real-world code examples to see how concepts are applied.
• Test Yourself: Use online platforms like LeetCode, HackerRank, or Codewars to practice coding problems.
• Mock Exams: Take practice exams to familiarize yourself with the format and types of questions asked.
• Understand Fundamentals: Make sure you have a strong grasp of Python's core concepts and syntax.

Remember, the key to excelling in this exam is a combination of understanding the fundamentals, gaining practical experience, and practicing regularly. Good luck!
