title: matplotlib ticks thickness
body: <p>Is there a way to increase the thickness and size of ticks in matplotlib without having to write a long piece of code like this:</p>
  
  <pre><code>for line in ax1.yaxis.get_ticklines():
      line.set_markersize(25)
      line.set_markeredgewidth(3)
  </code></pre>
  
  <p>The problem with this piece of code is that it uses a loop which costs usually a lot of CPU usage.</p>
