使用Twython从屏幕名称列表（Twitter API）获取用户ID

Question

我有下面的代码，它基于已知ID的列表查询Twitter API的屏幕名称。我想反过来：了解屏幕名称，并获取ID。

from twython import Twython 

# Paste your codes here 
app_key = '...' 
app_secret ='...' 
oauth_token = '...-...' 
oauth_token_secret= '...' 

# Create twitter thing to query 
twitter = Twython(app_key, app_secret, oauth_token, oauth_token_secret) 

# What to look up (Twitter id:s) 
ids = ["259784090","136953436","1219150098"] 

# Create a comma separated string from the previous list 
comma_separated_string = ",".join(ids) 

# Query twitter with the comma separated list 
output = twitter.lookup_user(user_id=comma_separated_string) 
username_list=[] 

# Loop through the results (Twitter screen names) 
for user in output: 
    print user['screen_name'] 

Answer 1

这是相同的API调用，但具有不同的参数。

The documentation for GET users/lookup says

返回作为由传递给USER_ID和/或SCREEN_NAME参数

假设你上述逗号分隔值指定为每个请求最多100个用户完全水合的用户对象，使用Twython是正确的（我不使用它自己）你应该可以调用...

# What to look up (Twitter screen_name:s) 
ids = ["john","paul","george","ringo"] 

# Create a comma separated string from the previous list 
comma_separated_string = ",".join(ids) 

# Query twitter with the comma separated list 
output = twitter.lookup_user(screen_name=comma_separated_string) 

username_list=[] 

# Loop through the results (Twitter screen names) 
for user in output: 
    print user["id_str"]
