- In this example, I have used the function def fib(n)
- We have initialized the first term to 0 and the second term to 1.
- The for loop is used to iterate the values till the given number
- At last, it will print fibonacci series
def fib(n): a = 0 b = 1 if n == 1: print(a) else: print(a) print(b) for i in range(2,n): c = a + b a = b b = c print(c) fib(10)To get the output, I have used print(c) to get the Fibonacci series. You can refer to the below screenshot for the output.

Python program to print fibonacci series using recursion
Here, we will see python program to print fibonacci series using recursion.
- In this example, I have used the function def Fibonacci(number)
- Here, if (number == 0) check whether the given number is 0 or not. If it is true, the function returns the value zero.
- elif (number == 1) check whether the given number is 1 or not. If it is true, the function returns the value one.
- A recursive function Fibonacci() is used to calculate the n term sequence.
- A for loop is used to iterate and calculate each term recursively.
- We will take the input from the user
def Fibonacci(number): if(number == 0): return 0 elif(number == 1): return 1 else: return (Fibonacci(number - 2)+ Fibonacci(number - 1)) number = int(input("Enter the Range Number: ")) for n in range(0, number): print(Fibonacci(n))To get the output, I have used print(Fibonacci(n)) to get the fibonacci series using recursion.

Python program to print fibonacci series up to n terms
Here, we will see python program to print fibonacci series up to n terms
- Firstly, we will allow the user to enter n terms
- We have initialized n1 to 0 and n2 to 1.
- If the number of terms is more than 2, we will use a while loop to find the next term in the sequence by adding the preceding two terms.
- After that, we interchange the variable and continue with the process.
n = int(input("Enter the n terms: ")) n1, n2 = 0, 1 count = 0 if n To get the output, I have used print(Fibonacci sequence) to get the fibonacci series up to n terms. You can refer to the below screenshot for the output
This is the Python program to print fibonacci series up to n terms.
Python program to print fibonacci series between 0 to 50
Now, we will see python program to print fibonacci series between 0 to 50

n1,n2 = 0,1 print(n1) while n2To get the output, I have used print to get the fibonacci series between 0 to 50. You can refer to the below screenshot for the output.
The above Python code, we can use to print fibonacci series between 0 to 50 in Python.
Python program to print fibonacci series using iteration
Now, we will see python program to print fibonacci series using iteration.
- In this example, I have used the function def fib(number).
- We have initialized first as 0 and second as 1.
- The while loop is used to find the next term in the sequence by adding the preceding two terms.
- And then update the value of the first and second.
def fib(number): count = 0 first = 0 second = 1 temp = 0 while count To get the output, I have used print to get the fibonacci series using iteration. You can refer to the below screenshot for the output.
The above Python code, we can use to print fibonacci series using iteration in Python.
Python program to print Fibonacci series without using recursion
Let’s see python program to print fibonacci series without using recursion.
- Firstly, the user will enter the first two numbers of the series and the number of terms to be printed from the user.
- Then print the first two numbers
- The while loop is used to find the sum of the first two numbers and then the fibonacci series
- Now, print the fibonacci series till n-2 is greater than 0.
n1=int(input("Enter the first number of the series: ")) n2=int(input("Enter the second number of the series: ")) n=int(input("Enter the number of terms needed: ")) print(n1,n2,end=" ") while(n-2): t=n1+n2 n1=n2 n2=t print(n2,end=" ") n=n-1To get the output, I have used print to get the fibonacci series without using recursion. You can refer to the below screenshot for the output.

Python program to print fibonacci series until ‘n’ value using recursion
Let see python program to print fibonacci series until ‘n’ value using recursion.
- In this example, I have used the function defrecursion_fib(num)
- Here, if num then return num
- The other terms are obtained by adding the preceding two terms. The n term is the sum of (num-1) and (num-2) terms.
- A recursive function recursion_fib is used to calculate the n term sequence.
- A for loop is used to iterate and calculate each term recursively.
def recursion_fib(num): if num To get the output, I have used print(recursion_fib(i)) to get the fibonacci series until ‘n’ value using recursion. You can refer to the below screenshot for the output.
