int is short for integer or whole number (1, -3, 72). What version of Python are you using? I've tested the code in sololearn's code playground and its working... I really dont know what could make those errors. Google search each error. Have fun :)

Oh, i got it. If you use just input, then the numbers wont be recognized (they are considered as a letters/string - so if you're using just input you will need to write "1" "2" etc.). You need to use int(input()). Also you have elses where you dont need them. So your code should look like this: a = [1,"Actualizar Stock"] b = [2,"Realizar Pedido"] c = [3,"Consultar Stock"] k = int(input("Ingrese opcion: ")) if k == (a[0]): print("nuevo menu") if k == (b[0]): print("New menu") if k == (c[0]): print("al fin") or I would do it on this way: print ("1.Actualizar Stock") print ("2.Realizar Pedido") print ("3.Consultar Stock") k = int(input("Ingrese opcion: ")) if k==1: print ("nuevo menu") if k==2: print ("New menu") if k==3: print ("al fin")

ok, i've run it, but it return this error: Ingrese opcion: Traceback (most recent call last): File "<stdin>", line 1, in <module> ValueError: invalid literal for int() with base 10: ' print("nuevo menu")' >>> ... ... File "<stdin>", line 3 if k == (b[0]): ^ SyntaxError: invalid syntax >>> File "<stdin>", line 1 print("New menu") ^ IndentationError: unexpected indent >>> ... ... But it appears that the general problem was the "else" use that i have, so i've tried your way but without int, bue got this after succefully putting a chouce (number) Traceback (most recent call last): File "<stdin>", line 1, in <module> NameError: name 'i2' is not defined What does int do?? thank you for your time :)
