Getting list assignment index out of range in my code

I'm trying to assign a value to a position in an existing list but I keep getting that my index is out of range. Probably something stupid but I have been 2 hours trying.

Here is my code (I'm getting the error from the last line:

test="2000 and was not However, implemented 1998 it until;9 8 3 4 1 5 7 2"
saver=[]
text=""
textList=[]
positionList=[]
num=0

for l in test.strip().split(";"):
    saver.append(l)
print saver
for i in saver[0].split(" "):
    textList.append(i)
print textList
for j in saver[1].split(" "):
    positionList.append(j)
print positionList

accomodator=[]*len(textList)

for n in range(1,len(textList)):
    n=int(n)
    if n not in positionList:
        accomodator[n-1]=textList[n-1]

Some variables I still havent used but I already declared them, so just ignore them.

Thanks in advance!

Length of accomodator is zero. It will give out of index error.

Try this:

accomodator=[]*len(textList)
#print str(len(accomodator)) + " "+str(len(textList))
i = 0;
while i<len(textList):
    accomodator.append([])
    i +=1

After creating accomodator, increase its length. Or if you know some efficient to increase its length, you can use it.

Your problem is this line:

accomodator=[]*len(textList)

Because an empty list multiplied by any number is an empty list:

>>> [] * 10
[]

You can initialize each element with some default value:

>>> [None] * 10
[None, None, None, None, None, None, None, None, None, None]

So the fix for your code is:

accomodator=[None]*len(textList)

And of course, 0 or -1 or any other value you like would work just as well.
