        3: "Earth",
        4: "Mars",

        7: "Uranus" , 
        8: "Neptune"
    }[id]

Possibility 2:

def get_planet_name(id):
    return ["Mercury","Venus","Earth","Mars","Jupiter","Saturn","Uranus","Neptune"][id-1]

Possibility 3:

def get_planet_name(id):
    if   id == 1: return "Mercury"
    elif id == 2: return "Venus"
    elif id == 3: return "Earth"
    elif id == 4: return "Mars"
    elif id == 5: return "Jupiter"
    elif id == 6: return "Saturn"
    elif id == 7: return "Uranus"  
    elif id == 8: return "Neptune"
