What library do use for interactions with Python? I think it might have an option to return binaries instead of charlists
But until then you can just charlist = 'abc'; string = "#{charlist}" or use to_string. To traverse maps, you can use Map.new()
So, to convert one map, you should write something like
Map.new(old_map, fn
{list, value} when is_list(list) ->
key =
try do
"#{list}"
except
# In case it's not a charlist
_ -> list
end
{key, value}
other ->
other
end)
