I don't understand your question but I will make a few guesses.

The code you show above creates a list whose elements are also lists:
In [12]: a = []

In [13]: for i in range(5):
   ....:     a.append([i])

In [14]: a
Out[14]: [[0], [1], [2], [3], [4]]

If you want a list containing all the values of i, just use the
range() function directly:
In [15]: range(5)
Out[15]: [0, 1, 2, 3, 4]

If you want a list containing a single value of i, create a new list
each time through the loop:
In [16]: for i in range(5):
   ....:     a = [i]
   ....:     print a

[0]
[1]
[2]
[3]
[4]
