Hey,
Could you please rephrase the question, because i dont understand what you said! because i think what you mean and know the answer but not sure!!
And if the answer is what Furman Doty said then NVM!!!

Answer 1

Do you mean how we set the variable before a for loop? like

y = 0
for i in range(x):
    y = y+1

why we do y = 0?
if so, its because otherwise when the loop tries to run

y = y+1

it wouldn't have a value for the y on the right side, so it couldn't give an answer.
If that wasn't your question, I'm not sure what you mean—please clarify.
