Use
fld = mydict.get(fldType, '?')

this will output the value from myDict if the key exists, if not it will
return None
Thanks this looks perfect - did not know dict.get()
You may also want to consider {}.setdefault -- that would collect the
fldType entries not defined.

I'm using python 2.5
I have a long list of if, elif, else. I always thought it was very NOT
pythonic. It's easy to read but not pretty.
for fldType in fieldList:
if "int" in fldType:
fld = "I"
elif "char" in fldType :
fld = "C"
elif "bool" in fldType :
fld = "B" .
