Python Fibonacci Generator

Question

I need to make a program that asks for the amount of Fibonacci numbers printed and then prints them like 0, 1, 1, 2... but I can't get it to work. My code looks the following:

a = int(raw_input('Give amount: '))  def fib():     a, b = 0, 1     while 1:         yield a         a, b = b, a + b  a = fib() a.next() 0 for i in range(a):     print a.next(), 

Answer 1

I would use this method:

Python 2

a = int(raw_input('Give amount: '))  def fib(n):     a, b = 0, 1     for _ in xrange(n):         yield a         a, b = b, a + b  print list(fib(a)) 

Python 3

a = int(input('Give amount: '))  def fib(n):     a, b = 0, 1     for _ in range(n):         yield a         a, b = b, a + b  print(list(fib(a))) 

Answer 2

You are giving a too many meanings:

a = int(raw_input('Give amount: ')) 

vs.

a = fib()        

You won't run into the problem (as often) if you give your variables more descriptive names (3 different uses of the name a in 10 lines of code!):

amount = int(raw_input('Give amount: ')) 

and change range(a) to range(amount).
