create a fibonacci function using a generator python code example

Example 1: python fibonacci generator

def fib(num):
    a = 0
    b = 1
    for i in range(num):
        yield a
        temp = a
        a = b
        b = temp + b


for x in fib(100):
    print(x)


def fib2(num): # Creates fib numbers in a list
    a = 0
    b = 1
    result = []
    for i in range(num):
        result.append(a)
        temp = a
        a = b
        b = temp + b
    return result


print(fib2(100))

Example 2: how to create fibonacci sequence in python

#Python program to generate Fibonacci series until 'n' value
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: create a fibonacci function using a generator python

#Learnprogramo
Number = int(input("How many terms? "))
# first two terms
First_Value, Second_Value = 0, 1
i = 0
if Number <= 0:
print("Please enter a positive integer")
elif Number == 1:
print("Fibonacci sequence upto",Number,":")
print(First_Value)
else:
print("Fibonacci sequence:")
while i < Number:
print(First_Value)
Next = First_Value + Second_Value
# update values
First_Value = Second_Value
Second_Value = Next
i += 1
