## Problem Formulation

The following problem formulation is taken from this Kata.

Design a recursive function called `replicate(times, number)`

that returns an array of repetitions of the `number`

argument.

For example, `replicate(3, 5)`

should return the list `[5, 5, 5]`

.

If the `times`

argument is negative, return an empty array.

Do not use loops to solve this problem.

## Code Solution

Here’s the code discussed in tihs video:

def replicate(times, number): # the forbidden way result = [] for i in range(times): result.append(number) return result def replicate(times, number): # recursive solution if times <= 0: return [] # base case and exception handling return replicate(times-1, number) + [number]

The first function uses the for loop, the second function uses the recursive solution with the base case and the recursion case.

## Where to Go From Here?

Enough theory. Let’s get some practice!

Coders get paid six figures and more because they can solve problems more effectively using machine intelligence and automation.

To become more successful in coding, solve more real problems for real people. That’s how you polish the skills you really need in practice. After all, what’s the use of learning theory that nobody ever needs?

**You build high-value coding skills by working on practical coding projects!**

Do you want to stop learning with toy projects and focus on practical code projects that earn you money and solve real problems for people?

🚀 If your answer is ** YES!**, consider becoming a Python freelance developer! It’s the best way of approaching the task of improving your Python skills—even if you are a complete beginner.
