Exercise for reference: 

Print out the text of this file http://www.pythonhow.com/data/universe.txt. Please don't manually download the file. Let Python do all the work.

Answer: 

import requests
response = requests.get("http://www.pythonhow.com/data/universe.txt", headers = {'user-agent': 'customUserAgent'})
text = response.text
print(text)

Explanation:

We're using the get method of the requests  library here, which produces a response  object in line 2. Then, in line 3, we apply the text property to that response object to get the loaded web page's text.
