I have an input with the name "city" which is a string and I need to make sure that if the user enters a number or does not type anything he receives an error message, as I could do?

Follows the code

import requests
import json
from googletrans import Translator


class Temperatura():
    while True:
        cidade = input("Escreva sua cidade para consultar o tempo: ")
        requisicao = requests.get("http://api.openweathermap.org/data/2.5/weather?q=" + cidade +
                                  "&appid=KEY")
        tempo = json.loads(requisicao.text)
        des = tempo['weather'][0]['description']
        hu = tempo['main']['humidity']
        t = tempo['main']['temp'] -273.15
        #tradução
        translator = Translator()
        des_t = translator.translate(des, dest='pt').text
        print('Condição do tempo:', des_t,',temperatura de', round(t),'graus','e umidade a',hu,'%')
python

  • That class Temperatura has a while just like that? No methods?

  • yes, but further down I have another input, which depending on the answer it to the class and starts another.

    It seems that you used class the wrong way there. This could be a function only.

  • Already corrected, thanks for the idea.

  • There are several other mistakes there, even if you change class for def no request will be made. recommend a better reading on the doc of the api. besides these two links for references classes and function

How your input is of the type str even if the user type 12345, for example, the program will not understand how int. So I suggest creating a variable and putting in there everything you want not accept, such as numbers, special characters, etc.

class Temperatura():

excluir = r"/\?%0123456789,."
while True:
    cidade = input("Escreva sua cidade para consultar o tempo: ")
    invalido = any(elem in cidade for elem in excluir)
    if cidade != '' and invalido == False:
        requisicao = requests.get("http://api.openweathermap.org/data/2.5/weather?q=" + cidade +
                                  "&appid=KEY")
        tempo = json.loads(requisicao.text)
        des = tempo['weather'][0]['description']
        hu = tempo['main']['humidity']
        t = tempo['main']['temp'] -273.15
        #tradução
        translator = Translator()
        des_t = translator.translate(des, dest='pt').text
        print('Condição do tempo:', des_t,',temperatura de', round(t),'graus','e umidade a',hu,'%')
    else:
      print('mensagem de erro')

    I suggest correcting the class that is not class either; and I need to say that it has become quite confusing to display an error message when valido is true. If it is valid, why would it make a mistake?

  • Truth haha. I corrected for invalido
