Get the GUID of a SharePoint List

I usually adopt this easy way of finding the GUID of a SharePoint List:
Go to the List or Library settings --> then right-click on the “Audience targeting settings” or “Information management policy settings” links and choose Copy Shortcut.
Paste this Copied Shortcut in a notepad.
You get a URL like this:
http://stdemo:36068/eaTest/_layouts/ListEnableTargeting.aspx?List={d50cb13c-4cf2-4569-9e5c-b9363c39bdb9}
The one in bold red between the braces is your List GUID

Updating a SharePoint List Item with a LookUp Column

I got this error
"Invalid data has been used to update the list item. The field you are trying to update may be read only" when I was trying to Update a List with a LookUp column called "Group".
This column looked up values from another list. The solution was to update the ID of the lookup column and it worked .
Here is the code snippet for the above:
SPList lst = listWeb.Lists[listName];
//Get the items of the list
SPListItem item = lst.Items.GetItemById(ItemID);
//Set the item of the list to the corresponding Group Name from the "LookUp" list .Note Group1 is the Internal name of the column Group
item["Group1"] = intGroupID;
listWeb.AllowUnsafeUpdates = true;
//The argument false for SystemUpdate informs the SPObject Model not to increment versions
item.SystemUpdate(false);
listWeb.AllowUnsafeUpdates = false;
