No, that will make the translated value be None (I guess that is what
you mean by null). You could then filter for these, for example
for key, value in Data.items():
Data[key] = [ transDict.get(i, i) for i in value if
transDict.get(i, i) is not None]
If you want to avoid double-fetching from transDict (if Data is huge
this might matter) then you could write out the loop or possibly use
something like
Data[key] = [ x for x in (transDict.get(i, i) for i in value) if x is
not None]
which makes an intermediate generator and filters that.
