The Fibonacci Sequence is computed based on the following formula:
f(n)=0 if n=0
f(n)=1 if n=1
f(n)=f(n-1)+f(n-2) if n>1
Please write a program using list comprehension to print the Fibonacci Sequence in comma separated form with a given n input by console.

def f(n):
if n == 0: return 0
elif n == 1: return 1
else: return f(n-1)+f(n-2)
n=int(raw_input())
values = [str(f(x)) for x in range(0, n+1)]
print ",".join(values)
