Ejemplo de número de Fibonacci en código python

Bienvenido a nuestra página, en este sitio hallarás la solucíon a lo que estabas buscando.

Ejemplo 1: python de secuencia de fibonacci

# WARNING: this program assumes the# fibonacci sequence starts at 1deffib(num):"""return the number at index `num` in the fibonacci sequence"""if num <=2:return1return fib(num -1)+ fib(num -2)# method 2: use `for` loopdeffib2(num):
	a, b =1,1for _ inrange(num -1):
		a, b = b, a + b
	return a


print(fib(6))# 8print(fib2(6))# same result, but much faster

Ejemplo 2: cómo crear una secuencia de fibonacci en python

#Python program to generate Fibonacci series until 'n' value
n =int(input("Enter the value of 'n': "))
a =0
b =1sum=0
count =1print("Fibonacci Series: ", end =" ")while(count <= n):print(sum, end =" ")
  count +=1
  a = b
  b =sumsum= a + b

Ejemplo 3: python fibonacci

defFibonacci( pos ):#check for the terminating conditionif pos <=1:#Return the value for position 1, here it is 0return0if pos ==2:#return the value for position 2, here it is 1return1#perform some operation with the arguments#Calculate the (n-1)th number by calling the function itself
        n_1 = Fibonacci( pos-1)#calculation  the (n-2)th number by calling the function itself again
        n_2 = Fibonacci( pos-2)#calculate the fibo number
        n = n_1 + n_2
 
        #return the fibo numberreturn n
 
#Here we asking the function to calculate 5th Fibonacci
nth_fibo = Fibonacci(5)print(nth_fibo)

Ejemplo 4: python de secuencia de fibonacci

num =1
num1 =0
num2 =1import time
for i inrange(0,10):print(num)
    num = num1 + num2
    num1 = num2
    num2 = num
    time.sleep(1)

Ejemplo 5: python de secuencia de fibonacci

# WARNING: this program assumes the# fibonacci sequence starts at 1deffib(num):"""return the number at index num in the fibonacci sequence"""if num <=2:return1return fib(num -1)+ fib(num -2)print(fib(6))# 8

Ejemplo 6: serie de fibonacci en python

# Program to display the Fibonacci sequence up to n-th term

nterms =int(input("How many terms? "))# first two terms
n1, n2 =0,1
count =0# check if the number of terms is validif 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
       # update values
       n1 = n2
       n2 = nth
       count +=1
