body: <p>I have a numpy array and I'm trying to multiply it by a scalar but it keeps throwing an error:</p>
  
  <pre><code>TypeError: unsupported operand type(s) for *: 'numpy.ndarray' and 'int'
  </code></pre>
  
  <p>My code is:</p>
  
  <pre><code>Flux140 = ['0.958900', 'null', '0.534400']
  n = Flux140*3
