python - How to iterate over a generator? -

assume big list , want iterate on it.

>>> x=[] >>> in x: print(x)

but because list big, using generator best way:

>>> g=(i in range(10)) >>> g.__next__() 0

but there problem number of times iterate. because don't know how many times should use g.__next__(), need more dynamic.

for example:

for in x:

it not important how long x loop iterate end.

how can iterate using generators?

you can use for syntax generators:

>>> g=(i in range(10)) >>> g <generator object <genexpr> @ 0x7fd70d42b0f0> >>> in g: ...     print ...  0 1 2 3 4 5 6 7 8 9
