python fib series till n code example
Example 1: fibonacci sequence python
def fib(num):
"""return the number at index num in the fibonacci sequence"""
if num <= 2:
return 1
return fib(num - 1) + fib(num - 2)
print(fib(6))
Example 2: fibonacci series in python
nterms = int(input("How many terms? "))
n1, n2 = 0, 1
count = 0
if nterms <= 0:
print("Please enter a positive integer")
elif nterms == 1:
print("Fibonacci sequence upto",nterms,":")
print(n1)
else:
print("Fibonacci sequence:")
while count < nterms:
print(n1)
nth = n1 + n2
n1 = n2
n2 = nth
count += 1
