我需要编写一个程序，询问要打印的斐波那契数字的数量，然后将其打印为0、1、1、2 ...，但我无法使其正常工作.我的代码如下所示:

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(),

推荐答案

我会使用此方法:

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)))
