title: Python: Create an array of substrings from an array
body: <p>I grabbed an array from the lines of a txt file. The problem is I only need the end of these lines. I'm still pretty new to Python so I'm not sure how to put these concepts together. Below is my best attempt, the first part works but the second falls apart.</p>
  
  <pre><code> with open("prices.txt") as f:
          readline = f.readlines()
  
   for seatCapacity in readline:
          seatCapacity = readline[10:]
  </code></pre>
