I wanted to take a variable and store different values. In this case, it would be 7 ages, how to do?

cont = 0
anos = 0
for c in range(1, 8):
    cont += 1
    anos = int(input('Em que ano a {} pessoa nasceu? '))

  • what you want to use is called array. Here are some examples: https://answall.com/questions/462627/impress%C3%a3o-de-matrices-in-python

  • intendi, then in case I can store different values with this matrix right, I’m beginner do not understand much yet

  • and access the values by the "index" :)

You would need to create a list to do so. And use .append() to add values to the list.

cont = []
for c in range(1,8):
    cont.append(c)
print(c)

Use lists (although similar to the array of other languages, the documentation calls the list):

idades = [] # lista vazia
for i in range(1, 8):
    idades.append(int(input(f'Em que ano a {i}ª pessoa nasceu?')))

Note that you don’t need the variable cont, use your own i which is being used by for (I think you missed that in your loop).

Another option is to create the list at once, using comprehensilist on:

idades = [ int(input(f'Em que ano a {i}ª pessoa nasceu?')) for i in range(1, 8) ]

  • Intendi, there for example if I want to print on the screen or make some sum with these variables I would need to put a number inside brackets that represent each person. EX: age[2] if I want to use the second stored value?

  • @Gabrieldasilvasantos In fact the indexes start at zero, so idades[0] is the first, idades[1] is the second, etc. And there’s a lot you can do with lists, I suggest you read this tutorial carefully: https://realpython.com/python-lists-tuples/

  • Obg by help. I will give a read and study more about. tmj ^-^
