title: Multiply by different factor depending on weekday or weekend
body: <pre><code>from datetime import datetime, time
  
  datetime.now()
  
  if 0 &lt;= now.weekday() &lt;= 4:
      cap = (((ConstantSeries(value=2574)) ))*(ConstantSeries(value=0.64))
  else:
      cap = (((ConstantSeries(value=2574)) ))*(ConstantSeries(value=0.46))
  
  capacity = cap
  </code></pre>
  
  <p>The constant series works well and is not the issue. I want to be able to multiply the time series by a different factor depending on whether it is a weekday or not</p>
