Running the code snippet below prints the names of all the parts in the item, but how do I get the item descriptions of all the parts?

import SystemWeaver as sw
import SystemWeaverAPI as swa

...
handle = sw.Common.SWHandleUtility.ToHandle(handle_str)
item = swa.SWConnection.Instance.Broker.GetItem(handle)
parts = item.GetAllParts()
for part in parts:
    print(part.Name) # How to get the item plain text descriptions for all parts?

 To clarify, the text that would appear in this box in the GUI:

Yes, thanks. There seems to be a problem with part.DefObj though. Printing at each step in the code yields this:

import SystemWeaver as sw
import SystemWeaverAPI as swa

...
handle = sw.Common.SWHandleUtility.ToHandle(handle_str)    
item = swa.SWConnection.Instance.Broker.GetItem(handle)
print(item)
parts = item.GetAllParts()
print(parts)
for part in parts:
    print(part)
    print(part.DefObj) 

 print(item)
=> SystemWeaver.ClientAPI.API.TswLibraryItem

print(parts)
=> SystemWeaver.Common.TswParts

print(part)
=> SystemWeaver.ClientAPI.API.TswPart

print(part.DefObj)
=> AttributeError: 'IswObject' object has no attribute 'DefObj' 

Sure but the problem I have is that running part.DefObj does not return a generic IswObject; instead, it raises the error: AttributeError: 'IswObject' object has no attribute 'DefObj'.

Here is what printing part outputs:

print(part)       => SystemWeaver.ClientAPI.API.TswPart
print(type(part)) => <class 'SystemWeaver.Common.IswObject'>
print(dir(part))  => ['Broker', 'DisplayImageIndex', 'Equals', 'FieldAsString', 'GetHashCode', 'GetType', 'Handle', 'HandleStr', 'IsNil', 'Name', 'ObjectAccess', 'Remove', 'Swot', 'ToString', '__class__', '__delattr__', '__dir__', '__doc__', '__eq__', '__format__', '__ge__', '__getattribute__', '__getstate__', '__gt__', '__hash__', '__init__', '__init_subclass__', '__le__', '__lt__', '__module__', '__ne__', '__new__', '__reduce__', '__reduce_ex__', '__repr__', '__setattr__', '__sizeof__', '__str__', '__subclasshook__', 'get_Broker', 'get_DisplayImageIndex', 'get_Handle', 'get_HandleStr', 'get_IsNil', 'get_Name', 'get_ObjectAccess', 'set_Name']

This seems strange. I would expect print(type(part)) to output <class 'SystemWeaver.Common.IswPart'>, not <class 'SystemWeaver.Common.IswObject'>.

For parts, it prints as expected:

print(parts)       => SystemWeaver.Common.TswParts
print(type(parts)) => <class 'SystemWeaver.Common.IswParts'>
