If you just have a user_id value you need to call the twitter API with the get_user(user_id) method. The returned User object will contain the username under screen_name.
如果您只有一个 user_id 值，则需要使用get_user(user_id) 方法调用 twitter API 。返回的 User 对象将包含 screen_name 下的用户名。
# steps not shown where you set up api
u = api.get_user(783214)
print u.screen_name
If you already have the User object from another API call just look for the screen_name.
如果您已经拥有来自另一个 API 调用的 User 对象，只需查找 screen_name。

Although OP clearly needs the username for just one id, in case if one wants to get usernames for a list of ids(<100), then:
尽管 OP 显然只需要一个 id 的用户名，但如果想要获取 id 列表（<100）的用户名，则：
def get_usernames(ids):
""" can only do lookup in steps of 100;
so 'ids' should be a list of 100 ids
"""
user_objs = api.lookup_users(user_ids=ids)
for user in user_objs:
print(user.screen_name)
For larger set of ids, you can just put this in a forloop and call accordingly while obeying the twitter API limit.
对于更大的 id 集，您可以将其放入for循环中并在遵守 twitter API 限制的同时进行相应调用。
