Hi,
When I run the following code in JScript, I see the result
JScript Code:
var WEAP = new ActiveXObject("WEAP.WEAPApplication");
WEAP.ActiveArea = "Tutorial";
var V = WEAP.Branch("\\Demand Sites\\City").Variables("Annual Activity Level");
var Temp = V.Value(2011, 1, "No LEAP Link");
print("Done. Value = " + Temp);

But when I run the equivalent code in python (following code) I get an error
Python Code:
import win32com.client
WEAP = win32com.client.Dispatch('WEAP.WEAPApplication')
v = WEAP.Branch('\\Demand Sites\\demand').Variables('Monthly Variation').Value(2015, 1)
print('Done. {}'.format(v))

Error: TypeError: 'float' object is not callable

Note) If I use Value without any parameter (like a property), it works but just return the first value (for example when I use MonthlyValues for its Expression {I mean using WEAP.Branch('\\Demand Sites\\demand').Variables('Monthly Variation').Value}

What should I do to read values of a variable (for individual timesteps) in Python?!?

Hi,

Have you solved this problem? I used the function named "ResultValue" instead.

v = WEAP.Branch('\\Demand Sites\\demand').Variables('Monthly Variation').ResultValue(2015, 1)

Do you have any advanced methods to read a large portion of data?

Hi all,

You can use "expression" function to export or assign data you want. If you want export data for individual timesteps, then use "for" loop.

This is an example to export 'Monthly Variation' for whole time:

v = [] #create empty list to save data
for i in range(WEAP.BaseYear, WEAP.EndYear+1):
for j in range(1,13):
v.append(WEAP.Branch('demand').Variables('Annual Activity Level')).expression
