Question

#what is the error in this code ?? I wanna make fibonacci series.
num = int(input())

def fibonacci(n):
for i in range(n+1):
print(i)
temp = i
res += temp
print(res)

fibonacci(num)
#output should be like :
0
1
1
2
3
5
8
13
...

Answer 1

To start you have to set res in fibonacci function (to 0 I assume)

Answer 2

Instead of fibonacci you generate triangular numbers (ignoring output from print(i))
