title: Give the number and fill the xth (x is the number) item in a list with '1',keep others empty
body: <p>for example, I have a list of data like this:</p>
  
  <pre><code>['81', '88', '99', '124', '144', '145', '216', '223', '225', '227', '231', '232', '233', '236', '238', '239', '240', '241', '242', '244', '245', '246', '247', '248', '249', '250', '251', '253', '254', '256', '257', '259', '260', '261', '264', '265', '266', '267', '268', '269', '270', '271', '272', '273', '274', '275', '276', '278', '279', '280', '281', '284', '285', '288', '296', '299', '304']
  </code></pre>
  
  <p>and I created a list, which contains 365 of ' ' by using  <code>julianList=[" "] *365</code></p>
  
  <p>Now, what I need to do is change the xth(x is number) of item in juLianList into '1'</p>
  
  <p>I use the following code</p>
  
  <pre><code>    julianList=[" "] *365
      EjulianList=list(enumerate(julianList))
  ##    print(EjulianList)
      print(julianList[2])
      for i in range(len(julian)):
          for j in range(len(EjulianList)):
              if julian[i]==EjulianList[j][0]:
                  julianList[j]='1'
      print(julianList)
  </code></pre>
  
  <p>but still get a list with 365 ' '
  like</p>
  
  <pre><code>[' ', ' ', ' ', ' ', ' ', ' ', ' ', ' ']
  </code></pre>
  
  <p>what's wrong with it?</p>
