The iter of function and next of function in python are explained in detail

list, tuple, and so on are iteratable objects, and we can get iterators for these iteratable objects through the iter() function. We can then keep making ⽤ to the obtained iterator; next() function to get the ⼀ The data. The iter() function is really just the call ⽤ ___ with iterable objects Method.

>>> li = [11, 22, 33, 44, 55]
>>> li_iter = iter(li)
>>> next(li_iter) 11
>>> next(li_iter) 22
>>> next(li_iter) 33
>>> next(li_iter) 44
>>> next(li_iter) 55
>>> next(li_iter)
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
StopIteration
>>> 

Note: When we've iterated through the end ⼀ After the data, adjust #12132 again; The next() function throws an exception to StopIteration to tell us that all the data has been iterated over. To hold the & # 12175; next() function.
