YouTube Live Session: Understanding Functions in Python for Data Analytics

Introduction:

Briefly introduce the importance of functions in programming and how they enhance code modularity and reusability.
Emphasize the relevance of functions in data analytics and how they can streamline data processing tasks.
Agenda:

Function Basics:

Define what a function is and why it's crucial in programming.
Discuss the structure of a function: function definition, parameters, and return values.
Built-in Functions:

Explore commonly used built-in functions in Python relevant to data analytics, such as len(), sum(), max(), min(), etc.
Demonstrate how these functions can be applied to analyze and manipulate data efficiently.
User-Defined Functions:

Teach how to create user-defined functions using the def keyword.
Explain parameters, arguments, and the importance of defining clear function purposes.
Illustrate how user-defined functions can be customized for specific data analysis tasks.
Lambda Functions:

Introduce lambda functions for concise and anonymous function definitions.
Show how lambda functions can be used in data processing tasks.
Function Scope:

Explain the concept of variable scope within functions and the differences between global and local variables.
Emphasize the importance of understanding scope for effective data analysis code.
