<PYTHON>이더레이터?? 제너레이터??

>>> a = [0,1,2,3,4,5,6,7,8,9]
>>> b = iter(a)
>>> b.next()
0
>>> b.next()
1
>>> b.next()
2
>>> b.next()
3
>>> b.next()
4
>>> b.next()
5
>>> b.next()
6
>>> b.next()
7
>>> b.next()
8
>>> b.next()
9
>>> b.next()
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
StopIteration

 

이더레이터..

 

리스트 ==  [iter()]  ==> 이더레이터

 

이더레이터.next() : 순차적으로 값을 반환

 

>>> def generateInt(n):
...     while n < 10:
...             yield n
...             n += 1
...
>>> g = generateInt(0)
>>> g.next()
0
>>> g.next()
1
>>> g.next()
2
>>> g.next()
3
>>> g.next()
4
>>> g.next()
5
>>> g.next()
6
>>> g.next()
7
>>> g.next()
8
>>> g.next()
9
>>> g.next()
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
StopIteration

 

제너레이터..

 

함수(value) ==   [yield]  ==> 제너레이터

 

제너레이터.next() : 순차적으로 값을 반환

 

--------------------------------------

 

결과가 똑같은 이더레이터와 제너레이터를 만들었다.
