# 尝试编写func()函数输出斐波那契数列的第十五个数是什么?
# 斐波那契数列:1,1,2,3,5,8,13,21,34,55……
def func(n):
print(func(15)) #调用函数并打印结果
if n<=2:
return 1
elif n>2:
'''
因为从第三项开始,每一项都是前两项所累加得到的和,
所以我们可以把他们看做第一项和第二项
'''
value = func(n-1)+func(n-2)
print("-----",n)
print("aa",func(n-1))
print("bb",func(n-2))
return value
print("---------------",func(3)) #调用函数并打印结果
