Python GeneratorNext, Function or Method ?
While in Python 2 it was possible to use both the function
next() and the
.next() method to iterate over the resulting values of a generator, the later has been removed with the introduction of Python 3.
Consider the sample generator:
def sample_generator(): yield "a" yield "b" yield "c"
In Python 2:
a = sample_generator() print(next(a)) # prints 'a' print(a.next()) # prints 'b'
But in Python 3:
print(next(a)) # prints 'a' print(a.next()) # AttributeError
