For-loop only returns last value

Question

I am trying this code on python:

N = 5

for n in xrange (0, N):
    a = [10 + n]
    
print(a[0])

The code returns 14 , and when I try to print(a[1]) I have a list index error. What I want is to be able to view a[0] , a[1] ... a[n] . When I write a=[10 + n for n in xrange (0,N)] it works but I don't understand the difference. Can anyone help on how to make the first method work?

Answer 1

You aren't appending to a list; you are repeatedly redefining which single-element list a refers to.

a = []
for n in range(N):
    a.append(10 + n)
