Can anyone explain this code please

Question

def tri_recursion(k):
if(k > 0):
result = k + tri_recursion(k - 1)
print(result)
else:
result = 0
return result

print("\n\nRecursion Example Results")
tri_recursion(6)

Answer 1

Sure! This is an example of a recursive function in Python that calculates the sum of the numbers from `k` to `1`. Here's how the code works:

1. The function `tri_recursion` takes one parameter `k`.

2. The function checks whether `k` is greater than 0. If it is, the function calculates the sum of `k` and the result of calling `tri_recursion` with the argument `k 1`. This is done recursively until `k` becomes 0.

3. If `k` is not greater than 0, the function sets the `result` to 0.

4. The function returns the `result`.

5. Finally, the function is called with the argument `6`, and the result is printed to the console.

So when you run this code, it should output:
Recursion Example Results
1
3
6
10
15
21
The output shows the sum of the numbers from 6 to 1, printed in descending order. The first call to tri_recursion calculates the sum of 6+5+4+3+2+1, which is 21.

Really I didn't get this one it's confusing more

Answer 3

Please tag "Python" instead of "aghsj".

Answer 4

Well there is a good explain about this but well maybe this help you

You call the function with 6 so the function take this 6 and add every number between 6 and 0 to this until you reached that 0. If you call the function with 10 it will do :
10+9+8+7+6+5+4+3+2+1
