Hello, I would like to make a code that when I typed for example, "product name", it checked if there is any word with the name I typed and returned a value, example "200 real". But I have no idea how to start, I’d be grateful if someone could help me!

You can use a dictionary to do what you want, see:

v = {
     'Celular':"200",
     "Bolsa":"200", 
     "Garrafa":"2"
     }                                    # Os valores também podem ser inteiros
r = input("Digite o valor do produto: ")  # Desde que aqui também seja

print("Por esse preço nós possuimos: \n")
for i in v.keys():
    if r == v[i]:
        print(i)

exit:

>>> Digite o valor do produto: 200
>>> Por esse preço nós possuimos: 
>>> 
>>> Celular
>>> Bolsa

    I think he wanted the opposite ; search by name and get the value

    But you can do it this way too, just reverse, in place of the product puts the value and in place of the value puts the product.

    I know, that’s why I commented on the question that your answer was beautiful ;-)

  • I wanted the opposite, yes, but I did what @Antony Gabriel said, reversed. Just a question, would be like after returning the value, ask to enter another name?

  • Yes, you can use one while for that reason.
