Comment (by vdelecroix):
Hello,
1. You can replace
{{{
keys1 = list(reversed(sorted(d1.keys())))
}}}
with
{{{
keys1 = d1.keys()
keys1.reverse()
}}}
2. Instead of looking at the length, you can do
{{{
if not keys1 and not keys2: return 0
if not keys1: return -1
if not keys2: return 1
}}}
3. Why the first key is treated differently?
Vincent
