Recursion only works when you have a termination condition. Otherwise,
it just loops endlessly (or more specifically until the stack runs out
of room). Still, you don't have a problem that even implies recursion,
just iteration.
For your simple case, there's a simple formula:
def find_temp(it):
return it+3
Methinks you have simplified the problem too far to make any sense.
import itertools
temp = 3
for it in itertools.count():
temp += 1
print it, temp
Warning: that loop will never terminate.
Is this what you were looking for? It uses recursion, and I used <=0
for the termination condition.
def find_temp2(it):
if it <=0: return 3
return find_temp(it-1)
