title: How to Add Incremental Numbers to a New Column Using Pandas
body: <p>I have this simplified dataframe:</p>
  
  <pre><code>ID   Fruit
  F1   Apple
  F2   Orange
  F3   Banana 
  </code></pre>
  
  <p>I want to add in the begining of the dataframe a new column <code>df['New_ID']</code>  which has the number <code>880</code> that increments by one in each row.</p>
  
  <p>The output should be simply like:</p>
  
  <pre><code>New_ID   ID   Fruit
  880      F1   Apple
  881      F2   Orange
  882      F3   Banana  
  </code></pre>
  
  <p>I tried the following:</p>
  
  <pre><code>df['New_ID'] = ["880"] # but I want to do this without assigning it the list of numbers literally
  </code></pre>
  
  <p>Any idea how to solve this?</p>
  
  <p>Thanks!</p>
