title: How to scrape a web site using Python, Requests and Xpath?
body: <p>I try to scrape first name + last name of people on this web page (<a href="https://www.meleenumerique.com/scientist_comite" rel="nofollow noreferrer">https://www.meleenumerique.com/scientist_comite</a>)  using the code below but it doesn't work. How can I determine what's wrong with it?</p>
  
  <p>This is the code I wrote</p>
  
  <pre><code>from lxml import html  
  import csv,os,json
  import requests
  url="https://www.meleenumerique.com/scientist_comite"
  r=requests.get(url)
  t=html.fromstring(r.content)
  
  title=t.xpath('/html/head/title/text()')
  #Create the list of speaker
  speaker=t.xpath('//span[contains(@class,"speaker-name")]//text()')
  
  print(title)
  print("Speakers:",speaker)
  </code></pre>
