Recursion in Python is a programming technique where a function calls itself to solve a problem. This method is particularly useful for breaking down complex problems into smaller, more manageable sub-problems. Each recursive function must have a base case to prevent infinite loops, ensuring that the recursion eventually terminates when the desired condition is met ¹⁴.

In Python, recursion can be applied to various scenarios, such as sorting algorithms, searching algorithms, and traversing data structures like trees. For example, the Fibonacci sequence can be calculated using a recursive function, where each number is the sum of the two preceding ones ⁴⁵.

Understanding recursion is essential for programmers and data scientists, as many coding interviews will include questions that require recursive solutions. Practicing with hands-on problems can help solidify your understanding of this concept ¹².
