How can I limit iterations of a loop in Python?

  1. How can I limit iterations of a loop in Python?

    You can use itertools.islice for this. It accepts startstop and step arguments, if you're passing only one argument then it is considered as stop. And it will work with any iterable.

  2. limit iterations of a loop in Python

    You can use itertools.islice for this. It accepts startstop and step arguments, if you're passing only one argument then it is considered as stop. And it will work with any iterable.

Method 1

You can use itertools.islice for this. It accepts startstop and step arguments, if you’re passing only one argument then it is considered as stop. And it will work with any iterable.

itertools.islice(iterable, stop)
itertools.islice(iterable, start, stop[, step])

Demo:

>>> from itertools import islice
>>> items = list(range(10))
>>> limit = 5
>>> for item in islice(items, limit):
    print item,
...
0 1 2 3 4

Example from docs:

islice('ABCDEFG', 2) --> A B
islice('ABCDEFG', 2, 4) --> C D
islice('ABCDEFG', 2, None) --> C D E F G
islice('ABCDEFG', 0, None, 2) --> A C E G

Method 2

Why not simply use

for item in items[:limit]: # or limit+1, depends
    print(item)    # or whatever function of that item.

This will only work for some iterables, but since you specified Lists, it works.

It doesn’t work if you use Sets or dicts etc.
