title: Functions: Renaming and processing
body: <p>So I'm having trouble trying to figure out this statement in Python. By re-typing the celsius_to_kelvin function. And Changing the name to kelvin_to_celsius.</p>
  
  <pre><code>def celsius_to_kelvin(value_celsius):
      value_kelvin = 0.0
  
      value_kelvin = value_celsius + 273.15
      return value_kelvin
  
  
  value_c = 0.0
  value_k = 0.0
  
  value_c = 10.0
  print(value_c, 'C is', celsius_to_kelvin(value_c), 'K')
  
  value_k = 283.15
  print(value_k, 'is', kelvin_to_celsius(value_k), 'C')
  </code></pre>
