Question

I’m blanking here. I want to grab all the users from the userbase, but then only loop through 10 of them (I’m leaving out code that would explain why I wouldn’t just grab 10 users from the db in the first place).

users = User.objects.all()
i = 0
while i < 10:
    for user in users:
        if user.is_active:
            # do something
            i += 1

This is creating an endless loop… What stupid detail am I missing?

If you want to look for 10 active users, you’re going to need to be a bit more clever.

for user in itertools.islice((x for x in users if x.is_active), 10):
  # do something
