title: Python foreach equivalent
body: <p>I am diving into Python and I have a question about foreach iteration. I am new to Python and I have some experience in C#. So I am wondering, if there is some equivalent function in Python for iteration all over all items in my collection, e.g. </p>
  
  <pre><code>pets = ['cat', 'dog', 'fish']
  marks = [ 5, 4, 3, 2, 1]
  </code></pre>
  
  <p>or something like this. </p>
