tweepy get_user does not work with a list of user_ids

Question

I am using tweepy library to pull informations about Twitter users. What I want is, given a list of Twitter ids, get the number of followers of each user that relates to the ids. The function looks like this.

infos = api.get_user(user_id=xxx)
return infos.followers_count

In the Twitter documentation, it says I can input a list of up to 100 user ids to get_user. Thing is, whatever I pass to that function other than a single id, I get the error

[{'message': 'Sorry, that page does not exist', 'code': 34}]

For example if I write:

infos = api.get_user(user_id=[user1,user2,user3])

I get the error. But if I write

infos = api.get_user(user_id=user1)

It works perfectly well. Did you encounter this problem before? Is the problem in Tweepy library? Should I use another library?

Thanks for your support

You need to use the function lookup_users for this, and the parameter is user_ids:

infos = api.lookup_users(user_ids=[user1,user2,user3])
