title: Converting a PD DF to a dictionary
body: <p>I have a pd dataframe as seen in image:
  <a href="https://i.stack.imgur.com/qRAMt.png" rel="nofollow noreferrer">image of data</a></p>
  <p>imported via the pd.read_csv method.</p>
  <p>I would like to convert it to a dictionary, where the key is 'Countries', and the value is a list of the numbers 1 to 300.
  How is the best way to do this? I have tried other methods listed on stack but since my df  doesn't have column headings it is not working</p>
