fibonacci numbers in python 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)
def fib2(num):
a, b = 1, 1
for _ in range(num - 1):
a, b = b, a + b
return a
print(fib(6))
print(fib2(6))
Example 2: how to create fibonacci sequence in python
n = int(input("Enter the value of 'n': "))
a = 0
b = 1
sum = 0
count = 1
print("Fibonacci Series: ", end = " ")
while(count <= n):
print(sum, end = " ")
count += 1
a = b
b = sum
sum = a + b
Example 3: 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 4: 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
Example 5: python fibonacci sequence generator
number1 = 0
print('1:', number1)
number2 = 1
for count in range(2, 101):
print(count, ':', number1 + number2)
number1 += number2
number2 = number1 - number2
Example 6: fibonacci sequence python
def recur_fibo(n):
if n <= 1:
return n
else:
return(recur_fibo(n-1) + recur_fibo(n-2))
nterms = 10
if nterms <= 0:
print("Plese enter a positive integer")
else:
print("Fibonacci sequence:")
for i in range(nterms):
print(recur_fibo(i))
