[PyQt] [Python plugin] menu items: actions binding with cycle

Hello all,

I'm developing a plugin for QGIS using:
- PyQt 4.3.3-2ubuntu4.1 
- Python 2.5.2
- Qt4

I'm populating a submenu with 4 items:

# create action for MCP submenu
self.actionmcp = QAction(QIcon(""), "MCP", self.iface.getMainWindow())
QObject.connect(self.actionmcp, SIGNAL("activated()"), lambda
method="mcp": self.showInterface(method))  

# create action for kernel href submenu
self.actionhref = QAction(QIcon(""), "Kernel
QObject.connect(self.actionhref, SIGNAL("activated()"),  lambda
method="href": self.showInterface(method))

...and so on.

The code is clearly self-similar. 
I tried to write a cycle to populate the menu, but it doesn't work.

mth = {"mcp":"MCP", "href":"Kernel h ref", "lscv":"Kernel h LSCV",
"hadj":"Kernel with adjusted h"}
[declaration of self.action* outside cycle]
for k, v in self.mth.iteritems():
 a = getattr(self,  "action" + k)
 a = QAction(QIcon(""), v , self.iface.getMainWindow())
 QObject.connect(a, SIGNAL("activated()"), lambda method=k:

I get no errors when running QGIS from a shell, but no submenu is
I've also tried to assign QAction(QIcon(""), v ,
self.iface.getMainWindow()) directly on getattr(), but Python didn't
allow to assign to a function.

Any suggestions?
