[python-win32] Python wn32com : How to give byRef parameters in object method and then get updated values

[Pascal]

Hello,

I'm not an expert, I just want to experiment python with SolidWorks
I'm trying to use its DLL with some success, but unfortunately, with 
some errors :
File "<COMObject <unknown>>", line 2, in Get5
com_error: (-2147352571, 'Type mismatch', None, 5)

I'm not sure about error comment, it's a translation because my python 
is in french language.

Here is a simplified extract of code :

app = win32com.client.Dispatch('Sldworks.Application')
part = app.ActiveDoc

docext = part.Extension
custPropMgr = docext.CustomPropertyManager('ma_config')
pNames = tuple(custPropMgr.GetNames) # return array of strings

for item in pNames:
       print(item) # string is well printed
       var1=''
       var2=''
       var3=False
       custPropMgr.Get5(item, False, var1, var2, var3) <== error happens 
here

I tried several things but I didn't reach to pass correctly the 
parameters to the Get5 method.
I think the problem is with the ByRef parameters, because I already used 
many method with ByVal parameters and it works rather fine.

I tried : var1, var2, var3 = custPropMgr.Get5(item, False)  as suggested 
somewhere but it didn't works

this method is described as below in the solidworks API help:
