Remove duplicates from a list of dictionaries when only one of the key values is different

Question

I have seen some similar answers, but I can\'t find something specific for this case:

I have a list of dictionaries like this:

[
 {\"element\":Bla, \         


        

Answer 1

Apologies for terrible variable names. There is probably a cleaner way but this should work

seen = {(item["element"], item["version"]): False for item in mylist}

output = []
for item in mylist:
    item_key = (item["element"], item["version"])
    if not seen[item_key]:
        output.append(item)
        seen[item_key] = True
