title: Adding item to Dictionary within loop
body: <p>Below data is grasped from webpage and containing entries as below(like a table with many rows): </p>
  
  <pre><code>entry1: key1: value1-1, key2: value2-1, key3: value3-1
  entry2: key1: value1-2, key2: value2-2, key3: value3-2
  entry3: key1: value3-1, key2: value2-3, key3: value3-3
  ......
  entry100: key1: value100-1, key2: value100-2, key3: value100-3
  </code></pre>
  
  <p>how can I use a dictionary to store this data? the data is from a list thus the 'dictionary append' should be done within a loop...</p>
  
  <p>here is my current solution:</p>
  
  <pre><code>case_list = {}
  for entry in entries_list:
      case = {'key1': value, 'key2': value, 'key3':value }
      case_list.update(case)
  </code></pre>
  
  <p>but the case_list in the end only contains the last case entry... Can somebody please help me on this?
  I would expect the case_list containing 100 entries w/o any overwriting among entries, and I will need to store it to DB afterwards. </p>
