I am trying to create a code on python that identifies the tone of the person based on emoticons (it is quite simple) however, it isn’t working. For example, if a person sent this message “i don’t know if i like bread 🙂 :-(“, the program would say that the person has a neutral tone (due to the fact that the happy and sad emojis are on the same amount), however my code answers that the person has a sad tone. Sorry if I made any mistake, english is not my first language.

mensagem = input()

divertido = 0
chato = 0 
a = 0
b = 0

a = mensagem.find(':-)')
b = mensagem.find(':-(')

divertido = divertido + a 
chato = chato + b

if divertido > chato:
    print("divertido")
elif divertido < chato:
    print("chateado")
else:
    print("neutro")
