Sort list of dictionaries by multiple keys with different ordering

Question

I need sort this list of dictionaries:

[ {K: 1, B: 2, A: 3, Z: 4, ... } , ... ] 

Ordering should be:

• K - descending
• B - descending
• A - ascending
• Z - ascending

I only found out how to sort all keys in ascending or descending (reverse=True):

stats.sort(key=lambda x: (x['K'], x['B'], x['A'], x['Z']))

Can anybody help, how to sort in key-different ordering?

Answer 1

if you have numbers as values, you can use this:

stats.sort(key=lambda x: (-x['K'], -x['B'], x['A'], x['Z']))

For general values:

stats.sort(key=lambda x: (x['A'], x['Z']))
stats.sort(key=lambda x: (x['K'], x['B']), reverse=True)
