यूआरएल ब्राउज़र में कोई समस्या नहीं के साथ खोला जा सकता है के साथ यूआरएल से डेटा लाने की कोशिश कर रहा हूँ। ..

लेकिन मैं (इस यूआरएल और किसी भी अन्य यूआरएल मैं कोशिश के लिए) एक त्रुटि हो रही है:

कोशिश उपयोग अनुरोध सत्र।

import requests 
MAX_RETRIES = 20 
url ='http://eutils.ncbi.nlm.nih.gov/entrez/eutils/einfo.fcgi' 

session = requests.Session() 
adapter = requests.adapters.HTTPAdapter(max_retries=MAX_RETRIES) 
session.mount('https://', adapter) 
session.mount('http://', adapter) 

r = session.get(url) 
print(r.content)
