Python list set value at index if index does not exist

Question

Is there a way, lib, or something in python that I can set value in list at an index that does not exist? Something like runtime index creation at list:

l =          


        

Answer 1

You cannot create a list with gaps. You could use a dict or this quick little guy:

def set_list(i,v):
    l = []
    x = 0
    while x < i:
        l.append(None)
        x += 1
    l.append(v)
    return l

print set_list(3, 'foo')
>>> [None, None, None, 'foo']
