fibonacci series in python

~~ This is the best Fibonacci sequence generator as you have all the option that 
till what number should this go on for ~~
  
a = 0
b = 1
f = 1
n = int(input("Till what number would you like to see the fibonacci sequence: "))
while b <= n:
    f = a+b
    a = b
    b = f
    print(a)
