Problem Statement: Write a Python program to print the Fibonacci sequence up to n terms.
Description: The Fibonacci sequence of numbers 0, 1, 1, 2, 3, 5, 8, 13, 21, 34 … formed by adding its previous two numbers.
It is defined by Fn = Fn-1+Fn-2.
Input: 7 Output: 0 1 1 2 3 5 8 Explanation: 0 and 1 are first two numbers in fibonacci sequence. Then next terms are calculated by 0+1=1 1+1=2 1+2=3 2+3=5 3+5=8 . . .
Hint: Initialize two variables with initial Fibonacci sequence 0 and 1. Then use for loop to print and add them for the next sequence.
Now you have the logic, you should try to write a Python program to find and print Fibonacci sequence up to n terms.
Python Program: Find Fibonacci Sequence using loop
n =abs(int(input("How many fibonacci numbers you want: "))) fib1 = 0 fib2 = 1 while(n>0): print(fib1) nextTerm = fib1+fib2 fib1 = fib2 fib2 = nextTerm n-=1
How many fibonacci numbers you want: 5 0 1 1 2 3
At first, we take the input in string form and convert to integer followed by calculating absolute value using
As described in the logic the first two Fibonacci numbers are 0 and 1.
Then we use while loop to print the Fibonacci number and find the next term using the formula.
While loop runs n times as entered by the user, printing n Fibonacci numbers.
