Question

how to print fibonacci series using while loop in python?

pls tell quickly

Answer 1

Answer:

fibonacci deries in Python

INPUT FORMAT:

Input consists of an integer

OUTPUT FORMAT:

A single line of output containing the Fibonacci series until 7 values.

SAMPLE INPUT:

7

SAMPLE OUTPUT:

0 1 1 2 3 5 8

PREREQUISITE KNOWLEDGE:while loop in Python and Recursion in Python

Method 1:Using a while loop

Algorithm for printing Fibonacci series using a while loop

Step 1:Input the 'n' value until which the Fibonacci series has to be generated

Step 2:Initialize sum = 0, a = 0, b = 1 and count = 1

Step 3:while (count <= n)

Step 4:print sum

Step 5:Increment the count variable

Step 6:swap a and b

Step 7:sum = a + b

Step 8:while (count > n)

Step 9:End the algorithm

Step 10:Else

Step 11:Repeat from steps 4 to 7

Python program to print Fibonacci series until 'n' value using while loop

#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

Input:

Enter the value of 'n': 5

Output:

Fibonacci Series: 0 1 1 2 3

Method 2: Using recursion

Recursive function algorithm for printing Fibonacci series

Step 1:If 'n' value is 0, return 0

Step 2:Else, if'n'value is 1, return 1

Step 3:Else, recursively call the recursive function for the value (n - 2) + (n - 1)

Python program to print Fibonacci series until 'n' value using recursion

#Python program to generate Fibonacci series Program using Recursion

def Fibonacci_series(Number):if(Number == 0):

return 0elif(Number == 1):

return 1else:

return (Fibonacci_series(Number - 2) + Fibonacci_series(Number - 1))

n = int(input("Enter the value of 'n': "))

print("Fibonacci Series:", end = ' ')

for n in range(0, n):

print(Fibonacci_series(n), end = ' ')

Input:

Enter the value of 'n': 5

Output:

Fibonacci Series: 0 1 1 2 3
