Efficient Code with Functions and Decorators

GlobalMart is a leading e-commerce company operating in over 120 markets across North America and Europe, specializing in technology, office supplies, and furniture.

One of the biggest challenges faced by GlobalMart data analysts is the need to write code that can be easily adapted and reused. As the GlobalMart website grows and evolves, data analysts often find themselves needing to analyze different sets of data. Without reusable code, this analysis can be time-consuming and error-prone.

To streamline their workflow, they decided to implement functions to encapsulate and reuse logic, thereby reducing code redundancy and simplifying code maintenance.

However, using functions alone may not fully address their needs. For instance, each function requires logic to:

• Log successful execution
• Measure the time taken
• Send an email notification upon completion

Adding this logic to every function increases redundancy and complicates the code by combining the additional tasks with the core function logic.

This is where decorators become essential.

Decorators allow the team to apply these additional features—like logging, timing, and notifications—across multiple functions without altering their core logic. This approach reduces redundancy, simplifies the code, and keeps the codebase clean and manageable.
