title: Convert year to seconds in Python
body: <p>I'm stuck on an assignment which needs me to convert an input of years and print the result in seconds. The error message I get when I run the function is: </p>
  
  <pre><code>'*TypeError: not all arguments converted during string formatting*'
  </code></pre>
  
  <p>I can't really get my head around what's wrong...</p>
  
  <pre><code>def ageInSeconds():
      """
      Reads the age and converts to seconds.
      """
      ageYears = int(input("Tell me your age, please: "))
      seconds = ageYears * (365*24*60*60)
      print("\nBatman says you age in seconds is: " % seconds)
  </code></pre>
