Set the index of a Python array -

i'm trying set index of array in python, isn't acting expected:

thething = [] thething[0] = 0 '''set thething[0] 0''' 

this produces following error:

traceback (most recent call last):   file "prog.py", line 2, in <module>     thething[0] = 0; indexerror: list assignment index out of range 

what correct syntax setting index of array in python?

python lists don't have fixed size . set 0th element, need have 0th element:

>>> thething = [] >>> thething.append(12) >>> thething [12] >>> thething[0] = 0 >>> thething [0] 

javascript's array object works bit differently python's, fills in previous values you:

> x [] > x[3] = 5 5 > x [undefined × 3, 5]
