Recursion In python
![To mitigate this, Python institutes a maximum limit for function calls i.e.
function calls. Imagine a recursive function that has no base case and
theoretically run forever if there was infinite memory, if trying to run this funct
Python, you will reach the 1000 call limit and the following error will be raise
can be read in the Traceback:
Recursion Error: maximum recursion depth exceeded.
It is possible in Python to see the current recursion limit as well as set the rec
limit.
# to view the recursion limit, do the following:
from sys import getrecursionlimit
print (getrecursionlimit()) # value printed would be 1000 by default
# to change the recursion limit, do the following:
from sys import setrecursionlimit
setrecursionlimit (2000)
print (getrecursionlimit()) # value printed will now be 2000
Compulsory Task 1
Follow these steps:
In a file called sum_recursion, create:
O a function that takes a list of integers and an integer as 2
arguments. The integer will represent an index point.
This function needs to add the sum of all the numbers in the list
up until and including the given index point by making use of
recursion and no loops.
O
Examples of input and output:
beriondev
adding_up_to([1, 4, 5, 3, 12, 16], 4)
=> 25
=> adding the number all the way up to index 4 (1 + 4 + 5 + 3 + 12)
adding_up_to([4, 3, 1, 5], 1)
