how to solve Error of list index out of range?-CodePudding

I have a problem, I write positive and negative numbers program.
I have no idea how to solve it... Here is my code: code:

T = []
N=int(input('Entre un nombre '))
NP=int(input('Entre un nombre positif '))
NN=int(input('Entre un nombre négatif '))
NP=0
NN=0
for i in range(1,N):
    if (T[i] <0 ):
        NN=NN 1
    else:
         NP=NP 1
int(print('les valeurs positives est ', NP))
int(print('les valeurs négatives est ', NN))

Help Me Please !!

               ^----0

1 - Start with 0, since list in python are zero-based:
2 - int it's a function convert characters into numbers

Your list T is empty because it is defined by T = []. You need to T.append(...) something in order to index it later.

Inside your for loop, you are trying to check an element that doesn't exist in the list.
