I am a fan of dict.setdefault() which has this logic built in:
Lev_List = {}
for Element in Elements:
keystr = 'Level_%i' % Element['Level']
Lev_List.setdefault(keystr, []).append(Element['Name'])
Also there is no need to create a string for the key, Element['Level']
is a fine key:
Lev_List = {}
for Element in Elements:
Lev_List.setdefault(Element['Level'], []).append(Element['Name'])
