The way that I solved this recently was to save the results of my search as stream and convert it into a list. So you would use a variable such as the following:
content = list(content)
After you have that you can use pandas to turn this into a dataframe, create a set of empty list and use a for loop to append each:
import pandas as pd
user = []
screen_name = []
for tweet in content:
user.append(content['user'])
user.append(content['screen_name'])
df = pd.DataFrame({'user': user, 'screen_name': screen_name})
df.head()
From there your data should be in a better shape to access the the first row of the data. I personally had success using the search tweets library and this method so that might be a better option for you if you are still running into blockers.
