Also, your code is not scalable. Now it’s fine since you have only two elements but for best practices, you should use a dictionary, JSON file, database, or the like.

I took my liberty to modify the output a bit:

name = tracker.get_slot("name")
country = tracker.get_slot("country")

data = {
    "america": "trump",
    "france": "macron"
}

message = "{} belongs to {}".format(name.title(), country.title())

if country.lower() in data.keys():
    leader_name = data[country.lower()]
    message = message + " and leader name is {}".format(leader_name.title())

dispatcher.utter_message(text = message)

return []

Or, to stay true to your code:

name = tracker.get_slot("name")
country = tracker.get_slot("country")

data = {
    "america": "Trump",
    "france": "Macron"
}

message = "not found in database!"

if country.lower() in data.keys():
    leader_name = data[country.lower()]
    message = "{} belongs to {} and leader name is {}".format(name, country, leader_name)

dispatcher.utter_message(text = message)

return []
