title: Why do I get TypeError: can't multiply sequence by non-int of type 'float'?
body: <p>I am typing to get a sale amount (by input) to be multiplied by a defined sales tax (0.08) and then have it print the total amount (sales tax times sale amount).</p>
  
  <p>I run into this error. Anyone know what could be wrong or have any suggestions? </p>
  
  <pre><code>salesAmount = raw_input (["Insert sale amount here \n"])
  ['Insert sale amount here \n']20.99
  &gt;&gt;&gt; salesTax = 0.08
  &gt;&gt;&gt; totalAmount = salesAmount * salesTax
  
  Traceback (most recent call last):
    File "&lt;pyshell#57&gt;", line 1, in &lt;module&gt;
      totalAmount = salesAmount * salesTax
  TypeError: can't multiply sequence by non-int of type 'float'
