How to limit loop when using cursor in python

I'm iterating over tweets using :

for status in tweepy.Cursor(api.user_timeline, screen_name='@realDonaldTrump').items():

But I want just the first 1000 items.

I can define an variable i=0 outside of the loop and then use if and i=i+1 to check if I've iterated enough. But it doesn't feel "pythony...", more C style

I've hoped there is some trick to it, like:

for status, i in (tweepy.Cursor(api.user_timeline, screen_name='@realDonaldTrump').items(), np.arange(10)):

Which of course doesn't work

Thanks

Use islice to do something similar to list[:10]:

from itertools import islice
cursor = tweepy.Cursor(api.user_timeline, screen_name='@realDonaldTrump').items()
for status in islice(cursor, 10):
    pass

To keep track of the index you can use the built-in enumerate:

for i, status in enumerate(cursor):
    pass
