Python program to print first n Fibonacci numbers
Write a Python program to accept a number from the user, and generate first n Fibonacci numbers.
What is the meaning of a Fibonacci series ..?
Fibonacci series: 0, 1, 1, 2, 3, 5, 8, 13 and so on…
The first number in the Fibonacci series is 0 (say f1) and the second number is 1 (say f2).
The next Fibonacci numbers are calculated as follows,
Repeat the following steps for n-2 times
f3 = f1 + f2
f1 = f2
f2 = f3
Source Code to print all Prime Numbers in the given range Program in Python
n = int (input("Enter the number of terms needed in the Fibonacci series: ")) if (n<0): print ("Enter a positive number") else: f1, f2 = 0, 1 if n == 1: print (f1) elif n == 2: print (f1,f2) else: print (f1,f2, end = ' ') for i in range (3, n+1): f3 = f1 + f2 print (f3, end = ' ') f1 = f2 f2 = f3
Enter the number of terms needed in the Fibonacci series: -10
Enter a positive number
Enter the number of terms needed in the Fibonacci series: 20
