This lightbulb will break with version numbers > 99999 ;)
Here are two alternatives:
result = sorted(
mylist,
key=lambda elem: (elem['name'], LooseVersion(elem['version'])),
reverse=True)
result = sorted(
mylist,
key=lambda e: (e["name"], tuple(map(int, e["version"].split(".")))),
reverse=True)
Personally, I prefer to not use a lambda:
def name_version(elem):
return elem['name'], LooseVersion(elem['version'])
result = sorted(mylist, key=name_version, reverse=True)
