Python Functions using global and comprehension

 In the earlier article, we have seen the use of global, and the different flavors of functions in Python.

• Using Global keyword
• Using Functions in Python

Let''s combine them and use comprehensions to reduce the total lines of code.

What are comprehensions in Python?

In Python, comprehensions are a concise and expressive way to create new sequences—like lists, sets, dictionaries, or generators—from existing iterables. They let you write elegant one-liners that would otherwise require multiple lines of loops and conditionals.

Comprehensions work like the Arabic language, read from right-to-left

🔍 Observations

• In the above screenshot, in modify(old_emp, new_emp), the execution happens in a sequential top-to-down manner.
• In modify_smart(old,new), the same execution happens in one-line from right to left

Let's highlight the comprehension in the modify_smart()

🔍 Investigating the above code: 

• for emp in company_employees: Iterate over each employee name in the list.
• new if emp == old else emp: If the employee name matches old, replace it with new; otherwise, keep it unchanged.
