# Python program to compute Fibonacci series using function.

**This program is one of the best for O-Level Practical. Read it carefully.**

**Program:**

def fab(x):

if x<2:

return 1

else:

return fab(x-1)+fab(x-2)

y=int(input("Enter a number :"))

for i in range(y):

print(i, "=", fab(i))

**Output:**

Enter a number :5

0 = 1

1 = 1

2 = 2

3 = 3

4 = 5
