You have two choices in Python: list or array
For simple lists of things use a list. If you want to
do vector math or matrix-type calculations look at the
array module.
For you simple example, here is the python code:
acctfile=[]
numoffiles=4
data=10
ct=1
for i in xrange(numoffiles-1):
acctfile.append(data)
ct=ct+1
data=data+ct
There are other ways, but this is closest to what you are
asking for (which I assume is a trivial example).
