title: Replacing individual characters in a print statement
body: <p><strong>I know the title is quite vague, but I have no idea how to sum what I want to do.</strong></p>
  
  <p>An example is a loading screen, I want to do something like this:</p>
  
  <pre><code>Loading assets - 10%
  </code></pre>
  
  <p>and then remove the output from the terminal and print</p>
  
  <pre><code>Loading textures - 20%
  </code></pre>
  
  <p>Every time I try something like this I get</p>
  
  <pre><code>Loading assets - 10%
  Loading textures - 20%
  </code></pre>
  
  <p>How can I do this?</p>
