The Fibonacci numbers, commonly refers as Fibonacci sequence, in which each number is the sum of the two preceding numbers, starting from 0 and 1.

The Fibonacci Sequence is the series of numbers:

0, 1, 1, 2, 3, 5, 8, 13, 21, 34, …

# Program to print Fibonacci sequence for 7 numbers
#fibonacci.py 
terms = 7
n1, n2 = 0, 1
count = 0
if terms <= 0:
    print ("Please enter positive term")
elif terms == 1 :
    print(n1,n2)
else:
    while terms > count:
        print(n1)
        nth = n1 + n2
        n1 = n2
        n2 = nth
        count +=1 

Output:

$ python fibonacci.py 
0
1
1
2
