You'll gain insight into scoping in Python, be able to write lambda functions and handle errors in your function writing practice. You'll wrap up each chapter by using your new skills to write functions that analyze Twitter data.

What you'll learn

• Assess error conditions in user-defined functions and apply try-except blocks or raise statements to handle exceptions effectively
• Distinguish between local, enclosing, global, and built-in scopes when accessing or modifying variables inside functions
• Evaluate the appropriate use of lambda expressions and higher-order functions such as map for concise data operations
• Identify the correct syntax for defining Python functions that accept single or multiple parameters and return single or multiple values
• Recognize how to implement default arguments, *args, and **kwargs to create flexible function interfaces
