python - Create set of keys from a list of dictionaries -

i wanted create 1 set list entries dictionaries. idea how in short python syntax?

from:

[{"a":45,"b":2,"c":"house"},{"a":36,"d":67,"e":"car"}] 

to:

{"a","b","c","d","e"} 

thanks!

try this:

lst = [ {"a":45, "b":2, "c":"house"}, {"a":36, "d":67, "e":"car"} ] { k d in lst k in d } => set(['a', 'c', 'b', 'e', 'd']) 

notice i'm returning unordered set, in question's body you're printing list keys, question's title states set of keys required.
