title: bulk download using python with requests
body: <p>I've been trying to download all the files on this page (<a href="https://apps.fs.usda.gov/fia/datamart/datamart_excel.html" rel="nofollow noreferrer">https://apps.fs.usda.gov/fia/datamart/datamart_excel.html</a>) in bulk , but am having some issues.</p>
  <p>All the filenames are the '{state abbreviations}.xlsm', so I can download a single file using requests using code like this:</p>
  <pre><code>import requests
  url = 'https://apps.fs.usda.gov/fia/datamart/Workbooks/WA.xlsm'
  r = requests.get(url)  
  with open('WA.xlsm', 'wb') as f:
      f.write(r.content)
  </code></pre>
  <p>I believe there should be a way to incorporate this into a for loop to get all of the files, but I'm at a loss. Any advice?</p>
  <p>Thanks!</p>
