Fibonacci sequence generator

The Fibonacci series is a classic series of numbers

where the 0th element is 0,

the 1st element is 1,

from there on, each element is the sum of the previous two elements.

For example, the following represents a Fibonacci series: 0, 1, 1, 2, 3, 5, 8, 13, 34, ...

Example 1

			
					n = int(input('How many Fibonacci ?'))

f1=0
f2=1
c=2

if n == 1:
    print(f1)
elif n == 2:
    print(f1,'n',f2,sep='')
else:
    print(f1,'n',f2,sep='')
    while c < n:
        f = f1+f2
        print(f)
        f1=f2
        f2=f
        c=c+1

Input :10

			
					How many Fibonacci? 10
0
1
1
2
3
5
8
13
21
34

Example 2: Function with generators

			
					a = int(input('Number : '))

def fibonacci(n):
    a, b = 0, 1
    for _ in range(n):
        yield a
        a, b = b, a + b

print(list(fibonacci(a)))

Input :8

			
					Number : 8
[0, 1, 1, 2, 3, 5, 8, 13]
