生成器的练习

一．练习一

def fibonacci(n):

num1=num2=1

count = 0

while count <= n-2:

num1, num2 = num2, num1+num2

count += 1

yield num1

F = fibonacci(12)

for x in,

二．练习2

def fibonacci(n):n:12
num1=num2=1 num1:1  num2:2
count=0
whilecount(=n-2：
num1, num2 = num2, num1+num2

count+=1
yield num1
F=fibonacci(12)#此时并不会调用函数

print(next(iter(F)))
print (next(iter(F)))
print(next(iter(F)))
print(next(iter(F)))
print(next(iter(F)))

运行结果

count=(int)1

n= (int）12

num1 = (int)1

num2 = (int)2

三.练习3

def fibonacci(n):
num1=num2=1
count=0
while count <= n-2:
num1, num2 = num2, num1 + num2

count +=1
yield num1
F=fibonacci(12)#此时并不会调用函数
for i in F:

print(i)
