Hi,
sorry, it may be a bit off topic. But I hope someone can help me with a
small problem.
I have two lists that I want to compare for differences between. Both
lists have some thousands of already sorted entries. I colud solve it
using two for-loops inside each other. For small lists this is ok. But
not for so many values.
Both lists are structured like this an only the keys should be compared
(is there a new key or one missing?):
a1['jimmy'] = { name : 'Jim', ... }
a1['johndoe'] = { name : 'John', ... }
a1['robert'] = { name : 'Robert', ... }
a2['chris'] = { name : 'Christian', ... }
a2['johndoe'] = { name : 'John', ... }
a2['robert'] = { name : 'Robert', ... }
a2['will'] = { name : 'William', ... }
Now I just need the differend keys (new/missing) compared a1 to a2.
The solutions I found seem to be to complex for my case. I need a simple
an effcient way to get the differences.
Might someone help me?
Tnx in advance,
Robert
