But that was really verbose, why didn't he contract everything
into one line?
dd = [dict(_name=k, **{a + str(i): d.get(k,{}).get(a,'') for a
in ('ver','rev') for i, d in enumerate((srv1, srv2))}) for k in
sorted(set(chain(srv1.keys(), srv2.keys())))]
:*)
Rewritten in without comprehensions it is something like:
dd = []
for k in sorted(set(chain(srv1.keys(), srv2.keys()))):
record = {'_name':k}
for a in 'ver','rev':
for i, d in enumerate((srv1, srv2)):
record[f'{a}{i}'] = d.get(k,{}).get(a,'')
dd.append(record)
