Day8:斐波那契数列

  eg : [1,1,2,3,5,8,...]

方法一:列表来存储

 1 def feib(n):
 2     f = [1,1]
 3     f[0] == 1
 4     f[1] == 1
 5     i = 2
 6     while i < n:
 7         s = f[i-1] + f[i-2]
 8         f.append(s)
 9         i += 1
10     return f
11 
12 n = 10
13 print(feib(n))

方法二:

 1 def feib(n):
 2     a,b = 1,1
 3     print(a,end = " ")
 4     '''for i in range(n-1):
 5         a,b = b, a+b'''
 6     while n-1:
 7         a , b ,n = b , a+b , n-1
 8         print(a,end = " ")
 9 
10 n = 10
11 feib(n)
