Python program to print the fibonacci series

n=int(input("How many terms you want to go? "))
n1, n2 = 0, 1
count = 0
if n <= 0:   # check if the number of terms is valid
   print("Please enter a positive number")
elif n == 1:
   print("Fibonacci sequence upto",n,":")
   print(n1)
else:
   print("Fibonacci series:")
   while count < n:
       print(n1)
       nth = n1 + n2
       # update values
       n1 = n2
       n2 = nth
       count += 1

     Output 1:
            How many terms you want to go? 9
