I'm having trouble resolving a
scope problem. I have a module, called from another script, with this
structure:
def parseFile(file, myLocation,
defaults):
#
initialisation.
ccyMappings = {}
def
getCcyMappings()
global
ccyMappings
# read values into
ccyMappings.
ccyMappings['CAN']
= ['CAD'] # for example.
def mapCcy(myCcy):
if ccyMappings.has_key(myCcy):
return ccyMapping['myCcy']
else:
return myCcy
if ccyMappings.has_key(myCcy):
return ccyMapping['myCcy']
else:
return myCcy
My problem is that, although
the ccyMappings dictionary is populated within the def getCcyMappings()
function, the value goes to 'None' when I leave it and so is not available when
the mapCcy function is called. I've used the global scope declaration
successfully before, but not with nested functions like this,
admittedly.
Any assistance gratefully
received.
Nick.
