How do I sort this list of tuples by both values?

Question

I have a list of tuples: [(2, Operation.SUBSTITUTED), (1, Operation.DELETED), (2, Operation.INSERTED)]

I would like to sort this list in 2 ways:

Answer 1

Since sorting is guaranteed to be stable, you can do this in 2 steps:

lst = [(2, 'Operation.SUBSTITUTED'), (1, 'Operation.DELETED'), (2, 'Operation.INSERTED')]

res_int = sorted(lst, key=lambda x: x[1], reverse=True)
res = sorted(res_int, key=lambda x: x[0])

print(res)

# [(1, 'Operation.DELETED'), (2, 'Operation.SUBSTITUTED'), (2, 'Operation.INSERTED')]
