And the OP might like to go a bit further, and as well as benchmarking
this style:
    array = []
    array.append("aaa")
    array.append("bbb")
    etc
try benchmarking this ... well "style" may not be the appropriate word
:-)
    array = []
    arrapp = array.append
    arrapp('aaa')
    arrapp('bbb')
    etc

Cheers,
