Hi All

I have the following code to sum the field name in the node input pin. I understood that there are nodes that can perform task easily, but I just curious and like to get it done in python
I have a sales column as the input node column and want loop over the column adding each sale in sales to variable total with the result 360 dollars.

Below would be an example in python

def sum_of_list(l):

  total = 0

  for val in l:

    total = total + val

  return total

  There is a guide to using the Python node that is installed with BRE named "Python Node Getting Started.pdf". It should be included in the following directory:

  <InstallDir>\docs 

  For example:

  C:\Program Files\Lavastorm\LAE6.1\docs

  The Python node is intended for advanced uses and it is recommended that other nodes (e.g. Agg Ex or Filter) are used as they can achive a simple summation of values without the code overhead of using the Python node. However, an example is attached for your reference.
